Question

Air enters a compressor operating at steady state at 1.05 bar, 300 K, with a volumetric flow rate
of 75 m/min and exits at 12 bar, 400 K. Heat transfer occurs at a rate of 12.5 kW from the
compressor to its surroundings. Assuming the ideal gas model for air and neglecting kinetic and
potential energy effects, determine the power input, in kW.

In a constant-volume process, 208 J of energy is transferred by heat to 1.07 mol of an ideal monatomic gas initially at 303 K. (a) Find the work done on the gas. (b) Find the increase in internal energy of the gas. (c) Find its final temperature. K
A monatomic ideal gas initially fills a V0 = 0.35 m3 container at P0 = 75 kPa. The gas undergoes an isobaric expansion to V1 = 1.5 m3. Next it undergoes an isovolumetric cooling to its initial temperature T0. Finally it undergoes an isothermal compression to its initial pressure and volume. 1. Calculate the heat absorbed Q2, in kilojoules, during the isovolumetric cooling (second process). 2.

A piston-cylinder assembly contains 0.7 lb of air initially at a pressure of 30 lbf/in² and a temperature of 100°F. The air is heated at constant pressure until its volume is doubled.

Air (a diatomic ideal gas) at 25.0°C and atmospheric pressure is drawn into a bicycle pump (see figure below) that has a cylinder with an inner diameter of 2.50 cm and length 53.5 cm. The downstroke adiabatically compresses the air, which reaches a gauge pressure of 8.00 x 10° Pa before entering the tire. We wish to investigate the temperature increase of the pump.
