The overall circuit voltage gain of a two-stage transformer-coupled amplifier is the a. difference between the second- and first-stage gains. b. sum of the first- and second-stage gains. c. second-stage gain divided by the first-stage gain. d. product of the first- and second-stage gains.

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.
