Atmospheric air is to be compressed and heated as shown in the figure before being fed into a chemical reactor, The ambient air is at 20 degrees Celsius and 1 bar, and is first compressed to 5 bar and then heated at a constant pressure to 400 degrees celsius. Assuming air can be treated as a single component ideal gas with Cv = 21 j / mol k, and the compressor operates adiabtically and reversibly, a) Determine the amount of work that must be supplied to the compressor and the temperature of the gas leaving the compressor b) Determine the heat load on the heat exchanger 1 bar, ambient air ----> 5 bar ----> Heater ---> 4 00 degrees celsius, 5 bar
