Ainput power of a 208v, 3hp, 4 pole 60 hz delta connected induction motor is 2500w at a 0.86 pf when it is running at 1740 rpm. the stator resistance is 2 ohms and th 2. e constant power loss: p aw+pmisc+ pcore) is 600w. find: (a) the stator copper losses (b) stator output/pag (c) rotor copper losses (d) pconv (e) pout (f) output torque

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.
