ROUND UP TO 4 DECIMAL PLACES. Draw and label the P-V and T-S diagrams. A spark ignition engine takes in air at 14.7 psia and 82°F. The engine takes in 1300 BTU/lbm during the combustion process. Inside the piston-cylinder the clearance is 11%. Determine the following: a. Pressure, specific volume & temperature at each state b. Work, per unit mass c. Heat Rejected
Please mention the table Number. So that i can verify the answer
An iron grade has a melting point of 2200°F. Its specific heat = 0.11 Btu/lbm°F, and its heat of fusion = 56.2 Btu/lbm. A 150-lbm block of this cast iron is to be melted. Determine how much heat is required to raise its temperature from 70°F to its melting point and transform it from the solid to liquid phase. Do not use a comma in your answer. Recall: Required heat H = mC(Tm – Ta) + mHf
