Consider an ideal Brayton cycle executed between the pressure limits of 1,130 kPa and 100 kPa and temperature limits of 293 K and 1,049 K with air as the working fluid. Determine the turbine work output (kJ/kg) of the cycle (to the nearest unit value) using cold-air-standard assumptions.

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?
