“Closed System-EB-Volume Change”

Air is contained in a vertical piston-cylinder assembly by a piston with a 4-in diameter and a weight of 300 lb,. The atmospheric pressure is 14.7 psia on top of the piston. A total of 4.13 Btu of energy as heat is transferred to the air and the piston rises at...

The heat transfer coefficient

The outer surface of the grill hood shown in the figure below is at 47°C and the emissivity is 0.93. The heat transfer coefficient for convection between the hood and the surroundings at 27°C is 10 W/m2K. Determine the net rate of heat transfer between the grill hood...

Linear pressure-volume process

Dr. Sigman discovers a new gas and wants to test in a piston-cylinder assembly. Two process paths are considered between the same end states, 1 and 2, where at state 1 the pressure is 10 bar, the volume is 0.1 m3, the internal energy is 400 kJ, and at state 2 the...

Relationship between pressure and volume

Air undergoes a process from an initial state 14.7 psia and 1000 in3 to a final state where 60 psia, and 320 in3. The relationship between pressure and volume during the process is pV” = constant. Determine the value of the constant n and calculate the work, in...

The work for the process in Btu

Carbon dioxide gas within a piston-cylinder assembly undergoes a process from an initial state of 5 psia, and 2.5 ft3 to a state of 20 psia, and 0.5 ft3. The path taken is indicated by the relationship P = 24 — 8V, where V is in ft3 and P is in psia. Determine the...

The mass of the piston

  Air is contained in a vertical piston-cylinder assembly. The atmosphere exerts a pressure of 14.7 psi on top of the 9-in-diameter piston. The absolute pressure of the air inside the cylinder is 16 psi. Determine the mass of the piston, in Ibm and gage pressure. The...
