Arotary actuator has the following physical data: outer radius of rotor rr = 0.80 in outer radius of vane rv = 1.7 in width of vane l = 0. 5 in if the torque load is t = 900 in∙lb, what pressure p must be developed to overcome the load?

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.
