A fluid at 0.7 bar occupying 0.09m³ is compressed reversibly to a pressure of (a) 3.5 bar according to a law pv" = constant. The fluid is then heated reversibly at constant volume until the pressure is 4 bar: the specific volume is then 0.5m³/kg. A reversible expansion according to a law pv = constant restores the fluid to its initial state. Sketch the cycle on a p-v diagram and calculate: i) the mass of the fluid present; ii) the value of n in the first process; 1. iii) the net work of the cycle.
The solution (298.349) is incorrect as well.
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A steam power plant receives heat from a furnace at a rate of 280 GJ/h. Heat losses to the surrounding air from the steam as it passes through the pipes and other components are estimated to be about 8 GJ/h. The waste heat is transferred to the cooling water at a rate of 170 GJ/h. Problem 06.017.a - Net power output of steam power plant Determine the net power output. (You must provide an answer before moving to the next part.) The net power output is MW.

Specific fuel consumption of a four-stroke internal combustion engine at a given rotational speed is 0.322 kg/kW-h value is minimum. Spindle power at this rotation rate is 123 kW, volumetric efficiency is 95% and air-fuel rate is 15. The number of rotations of this engine is calculated by subtracting 1.5 from the number of rotations giving the minimum specific fuel consumption. time, spindle power 162 kW, specific fuel consumption 0.394 kg/kW-h and volumetric efficiency 85%. a) Calculate the air-fuel ratio in this case. and By what percent has the efficiency of the engine changed?
