Document Summary
Me 235 exam 1, oct 12, 2004: atreya and c. borgnakke. I have observed the honor code and have neither given nor received aid on this exam. Signature:___________________________________________: [35%] air sucked into an internal combustion engine piston cylinder arrangement essentially goes through two different processes, starting at 227oc, 1000 kpa with a volume of 0. 1 m3 the air is heated up to. You may use constant specific heats to solve this problem cp0 = 1. 004 & cv0 = 0. 717: [35%] a piston cylinder has the water volume separated into va = 0. 2 m3 and vb = It is heated up to 60oc at which point the specific volume is 0. 03002 m3/kg. a) find the final pressure. c) find the work in the process: find the final volume, find the heat transfer in the process. Process equation: v = c; 1w2 = p dv = 0 . E2 - e1 = m(u2 - u1) = 1q2 - 1w2 .
