Acertain room has 2kw heat loss is to be heated by air collector of single glass cover and w=1.5m, l=3m, h=5cm 1920 w/m, 7,-25*c, ra 0.87, 4.-4.5 w/m. x,6,-0.9, & .=0.9. # the mass flow rate of air=0.27 kg/s, and inlet a temperature 45*c, will the collector is sufficient? estimate the supply air temperature and overall system efficiency. b: discuss briefly, based on the performance analysis, "a major parameters taking into account to improve the soli collectors

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

How is zig zagging a form of acceleration?

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
