A stream of water vapor flowing at a rate of 250 mol/hr is brought from 600°C and 10 bar to 100°C & 1bar. PART A) Estimate the required cooling rate (kW) using the steam tables.

PART B) Estimate the required cooling rate (kW) using the CP of water vapor.

CP (water vapor) [kJ/mol°C] = 0.03346 + 6.88*10-6T

PART C) What is the physical significance of the difference between the values calculated in Parts A and B?

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
