Steam enters a nozzle operating at steady state at 140 psia and 600 °f with a velocity of 100 ft/s. the pressure and temperature at the exit are 40 psia and 350 °f, respectively. if the nozzle can be considered to be adiabatic, determine its 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?
