Propane (c3h3) burns completely with 230% of theoretical air entering at 74°f, 1 atm, 50% relative humidity. the dry air component can be modeled as 21% o2 and 79% n2 on a molar basis. the combustion products leave at 1 atm. determine the dew point temperature of the products, in °f.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
