An induction motor has the following information on the nameplate:

2hp, 1730 rpm, 3-phase, 60hz, 220/440v, 6.2/3.1a.

calculate the rated, torque, rated slip, the input realand apparent power (assuming a pf = 0.85) and the full-load efficiency.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?

What is the main objective of using reheat rankine cycle?
