Find the quanity of heat required to produce 79% dry steam at 8000 kpa from feedwater at 50 degrees celcius ?.

Air in an ideal diesel is compresses from 8 liters to 0.15 and then expands during the constant pressure heat addition process to 0.3 L. Under cold air standard conditions, find the thermal efficiency.

I need answer in handwritten

Which is more efficient, dry or wet standardammonia vapor compression system in such away it is dry after compression. Justify answerby computation.

A 7.162M British Thermal Unit per hour is required for a gas turbine power plant in Palawan wherein hot air enters at the compressor section at 3.4 psig, 300K. Considering a pressure ratio of 9 and the turbine area receives the hot gases at 1742 deg F, find the required air flow in lb/min.
