Abasic disc clutch is to be designed to transmit a torque of 100 lbf-in. the outer ring diameter is to be 4 inches. the values for the molded friction material are to be pmax = 200 psi and f = 0.25. find appropriate values for the ring inside radius (ri) and the clamping force (f).

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
