An uninsulated piston-type air compressor operates in a steady flow process from 0.100 MPa, 300. K to 2.00 MPa, 540. K. Use the gas tables to determine per unit mass flow rate,
a. The power required.
b. The heat transfer rate.
when the entropy production rate per unit mass flow rate is 0.538 kJ/(kg ·K) and the mean cylinder external wall temperature is 432 K.
Determine (a) the coefficient of performance of the heat pump. (b) the coefficient of performance of a reversible heat pump operating between hot and cold reservoirs at 708F and 308F, respectively, and the corresponding rate at which energy wo..
A uniform, thin, rigid bar AB having mass M and length b is attached to a uniform flexible beam BC. Assume a small transverse displacement v(x, t). Using appropriate diagrams (free-body and kinematics), determine the boundary conditions for the be..
a cylinder is confined in a cylinder by a spring-loaded frictionless piston so that the pressure in the fluid is a

Fluid is flowing in the pipe has two areas. The velocity of the fluid flowing in the larger area is 4 ft/s. The radius of the larger area is 4 inches. The radius of the smaller section is 2 inches. What is the velocity of the fluid in the small secti..
Air, modeled as an ideal gas, is compresses at steady state from 1 bar, 300 K, to 5 bar, 500K, with 150 kW of power input. Heat transfer occurs at a rate of 20 kW from the air to cooling water circulating in a water jacket enclosing the compressor. N..
