Rigid tank of the volume v= 0.3 0 is filled with saturated water vapour at t. 200°c. a valve at the bottom of the tank is opened, and ri, lcin 3 sat, lined liquid water at t= 200°c is slowly injected. heat is exchanged between tank and surroundings at such a rate that temperature of the process remains constant. determine the amount of heat that must be exchanged by the time the total mass of the medium in the tank

What precautions should you take to prevent injuries when dealing with heavy loads?

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
