One kilogram of air is heated reversibly at constant pressure from an initial state of 300 k and 1 bar until its volume triples. calculate w, q, ∆u, and ∆h for the process. assume for air that pv/ t = 83.14 bar cm3/ mol k and cp = 29 j / mol k. ans [w= 74.895 kj; q= 602.08 kj; δu= 12.41 kj/mol; δh=17.4 kj/mol] 3.
b)1 kg of saturated water vapour at 3.166 kpa and 25oc enters a compressor and discharges at 101.33 kpa and 100 oc (saturated water vopur). assuming that no heat is release during the compression, how much compression work are required?
