A water tube boiler has a capacity of 1000 kg/hr of steam. The factor of evaporation is 1.3, boiler rating is 200%, boiler efficiency is 5%, heating surface area is 0.91 m²/boiler Hp, and the heating value of fuel is 18,400 Kcal/kg. The total coal available in the bunker is 50,000 kg. Determine total number of hours to consume the available fuel. 1.
Pls.answer thank you! A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5 KW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 KJ/hr. There are 10 light bulbs in the room, each with a rating of 100 watts. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 KJ/hr. If the room air is to be maintained at a constant temperature of 21°C, determine the number of window air-conditioning units required.
You are replacing an HVAC system in your building. The system is a steam system that consists of a boiler that feeds several air-handling units. The total heating load for the building is 3613 thousand Btuh. The building has 15 floors in total. What is the required total flow rate (in lb/hr) of the steam to satisfy the heating load?
A particular frost-free refrigerator uses about 745 kWh of electrical energy per year. Express this amount of energy in unit cal.
Q3/Answer by true or false : 1) All water systems using fan coil units are suitable in buildings requiring individual room control and consume less space compared to all air systems. 2) All air conditioning systems make use of an economizer. 3) With 100 % re-circulated air, some time, the room ADP is equal to coil ADP and the load on the coil is equal to the load on the room. 4) The sensible load affects dry bulb temperature, while the latent load affects the moisture content of the conditioned space. 5) A single zone, single duct, constant volume system can be used either for cooling or for heating, but not for both cooling and heating simultaneously.
A reversible refrigeration cycle operates between cold and hot reservoirs at temperatures Tc and TH, respectively. (a) If the coefficient of performance is 10 and Tc- -40°F, determine TH, in °F. (b) If Tc- -30°C and TH -30°C, determine the coefficient of performance. (c) If Qc - 500 Btu, QH-600 Btu, and Tc -20°F, determine TH, in °F.

select if true or false for the following questions 1. For a standard condenser in a refrigeration system, the thermal energy (in J) is equal to the mass (in kg) multiplied by the change in enthalpy across the condenser (in J/kg). 2. Consider a basic refrigeration cycle: Since it requires less work to compress a liquid than a vapor, the entire refrigeration process would work better if the compressor was replaced with a pump. All else being equal, increasing the mass-flow rate of refrigerant will increase the rate of heat transfer at the system’s evaporator. All of these (except, of course, the one labeled, “None of these.”) None of these.
2) A heat pump with the amount of heat of liquid refrigerant (mix) when it will enter the expansion of 480 Btu/lb. while the amount of heat from the refrigerant vapor after leaving the evaporator is 412 Btu/lb. What is the coefficient of performance (COP) if the heat amount of the superheated refrigerant after being compressed by the compressor has a value of 572 Btu/lb?
