- Q:the pressure is around 23 bar(g)
- I don't believe there is an overall heat transfer coefficient for hydrogen. That term is normally used for a situation where there is heat transfer that is made up of multiple types of heat transfer and usually through a given surface such as a wall, heat exchanger surface or similar situation. The reference is one of several that gives conductivity information.
- Q:has anyone ever used a fireplace hearth heater?
- I have tried them but they are pretty much a waste, and the 500% more efficient claim on the website link made me laugh. The fireplace heat exchanger without the fan is a total and complete waste of money. From my experience with that variety they just make it more difficult to get the right size log in the firebox. I noticed no noticeable heat exiting the tubes and entering the room. The blower variety I tested is a little better, but keep in mind it is only going to raise the efficiency of the fireplace by maybe an additional 10% at best. And considering most fireplaces operate in the realm of -10% to 15% efficiency you are not exactly harvesting the heat. It is an unfortunate but scientific fact that most fireplaces are pretty much wood toilets and not heat sources, but they sure look neat. People have heated with them for centuries but people have also have ridden horses for centuries too (until something better came along). When it comes to hearth equipment I know what i like and what I expect for the investment and i would fit these units into the I wouldn't waste my money category. It doesn't mean they are worthless it just means if you want meaningful heat from your fireplace you can do alot better by saving your money for an insert.
- Q:In a well-insulated heat exchanger, the overall heat transfer coefficient is 6.6 kW/m2.°C and the total effective heat transfer area is 1.5 m2. The temperature difference between the inlet and exit of the minimum fluid (the fluid with minimum thermal capacity) is 60 ?C and the corrected LMTD of the heat exchanger is 30 °C. Which one about the thermal capacity of the maximum fluid (the fluid with the maximum thermal capacity) is correct?A.The given information is not enough to answer this questionB. Cmax = 4950 W/°CC .Cmax lt; 4950 W/°CD. Cmax gt; 4950 W/°C
- I assume the temperature difference for minimum fluid is for cold or hot stream only. Not the difference between them (the cold and hot). U = 6.6 kW/m^2.°C A = 1.5 m^2 ΔT_min = 60 deg. C LMTD = 30 deg. C Q = U*A*LMTD Q = 6.6*1.5*30 Q = 297 kW Heat transfer from cold/hot fluid. Q = Cp_min*ΔT_min Cp_min = 4950 W/°C With, LMTD = ΔT2 - ΔT1 / ln(ΔT2/ΔT1) 30 = ΔT2 - ΔT1 / ln(ΔT2/ΔT1) We have only one equation, with two unknows, temperatur inlet and outlet for maximum fluid, thus it can't be solved. Cp_,max = Q/ΔT_max Cp_max can't be solved because ΔT_max is unknown. So the answer may be A or D. A. The given information is not enough to answer this question D. Cmax > 4950 W/°C However if one just need for range capacity, then the answer is D.
- Q:The Expedition's AC is full charged and no links, but when you put the AC on it blow heat as if the heater was on. Now warm air but hot air like the heater is on. If you can help. Thanks
- This is potentially very damaging to the compressor so get it fixed before trying to run A/C. What's probably happening is the condenser fan is not coming on due to being broken, bad relay, etc. That's easy to check for yourself, it's in the same area and looks the same as the radiator fan. It should come on and off when you turn on and off with A/C switch. You might also notice that A/C gets cool when you are driving fast but heats up when waiting at a red light. The reason it hurts the compressor is a little complex but here goes - The condenser is supposed to convert the refrigerant from hot, high-pressure gas to liquid so it can be evaporated into gas later in another heat exchanger inside the dash. If the condenser is overheated due to lack of a working fan on it, then the refrigerant stay as gas and passes through the orifice tube at lower pressure, but still a hot gas. This stuff hits the relatively cooler coils in the evaporator and takes the opportunity to condense instead. Condensation throws a lot of heat (latent heat of phase change) into the air blowing out in your face, and sends still-hot liquid into the compressor. Compressors like to see gas coming in because they like to compress stuff. Liquid is not compressible like gas, so the little fins that press the gas together get damaged when they try to compress the liquid. Also, the heat not shed in the condenser is going to increase the heat load on the compressor, which is really what kills it. This will eventually (if not already) send out small metal particles through the system requiring the compressor and a few other parts to be replaced or cleaned out. Since you have an O-tube system there's no other A/C reason for the hot air to be produced. So if you confirm the condenser fan is OK, then you have an electrical/computer issue with the heater controls.
- Q:actually i want to know how to define the power required for air cooled heat exchanger fan.thanx!
- So you want to specify the AC power needed for the fan? Decide how much air flow you need, and how big the blades are, then search for a fan on the internet that meets that spec.
- Q:i do not know their shape i hope you will attach a picture thanks in advance please it is urgent
- plain tubes in heat exchangers does not have any thing attached to their exterior wall to dissipate energy. The only area they use to dissipate energy is their exterior area. While finned tube have some extra mass attached to their wall so as to increase area to increase heat dissipation. Car radiator has fins attached to their wall , the silvery thing you see, motor cycle engine is also finned to increase heat dessipation. while plain tube is very rarely seen.
- Q:10yrs parts/ 10yrs compressor/ 10yrs coil/ 1yr labor or spend $1600 more for a unit with10yrs parts/ 10yrs labor/ 15yrs coil
- I wouldn't spend the extra money, if you do you get the extended warranty you will need your equipment serviced every year to keep the warranty good, which to be honest with you - the newest equipment on the market is close to maintenence free and smart enough to self diagnose itself and the furnace will shut off if anything unsafe may occur. so with that said add 10 years of maintenence, twice a year, $80 a check-up is extra $1600 + 2400 = $4,000 worse case before 10 years - the compressor needs changed, cost of labor to change a compressor would definitely be under a $1000. plus perhaps a few service calls in between if something breakes down , so add another $500 roughly, fyi - a majority of the things that break down on a unit are not something that can be prevented against. just become good with changing your filters and rinsing your outdoor coil. A lot of other service techs will thumbs this down, but in my opinion when I service newer equipment, it almost feels pointless.
- Q:what is the function of heat exchanger in gas turbine?
- For my knowledge there are 3 efficiencies in thermal power generation system thermal efficiency--- energy absorbed in relevant to the energy given to the system through fuel.. less than 1 due to the heat loss to the environment and the heat in exhaust gas..... mechanical efficiency-- is less than 1 due to the friction in rotationary parts ( turbine and generator) electrical efficiency-- is less than 1 due to core and copper losses overall efficiency is given by the multiplication of all three.... which is electrical power outcome to the given thermal power heat exchanger transfer heat from on source to another (ex heat of the burning fuel to water)
- Q:What is the heat transfer expected from a ground-loop system that has a 10 gpm flowrate, a heat exchanger inlet temperature of 45°F, and a heat exchanger outlet temperatureof 56°F? Assume that the system uses pure water.A. 52,750 Btu/h C. 55,000 Btu/hB. 53,350 Btu/h D. 56,450 Btu/h
- Use the open system calorimetry formula: Q_dot = m_dot*(h2 - h1) h2 and h1 can be looked up as enthalpy based on given temperatures. However, an approximation of calorically perfect water exists, with a constant c_p. Since water is a liquid, you can assume (if you must) that there is no difference between isochoric specific heat (c_v) and isobaric specific heat (c_p). Should it vaporize, you must understand the difference. Including definition of c_p, we can replace h with c_p*T: Q_dot = m_dot*c_p*(T2 - T1) Since we're given V_dot instead of m_dot, include the factor of rho, which relates the two: Q_dot = rho*V_dot*c_p*(T2 - T1) We are given V_dot in gallons per minute. Convert to a m^3/sec because metric units are nicer. Do the same with temperatures. T2:= 13.3333 C T1:= 7.22222 C V_dot := 6.30902e-4 m^3/sec Look up c_p and rho for water: c_p := 4184 Joules/kg-K rho:= 1000 kg/m^3 Calculate to find result: Q_dot = 16131 Watts Convert to BTU/hr: Q_dot = 55,043 BTU/hr Answer is C
