A rigid tank contains 1 kg of H20 at 100 kPa, x=0.1. Given that the tank can withstand a maximum internal pressure of 2 MPa, determine
(a)the maximum temperature to which the steam in the tank can be heated, and
(b)the amount of heat transfer necessary to reach this maximum pressure.
(c)Draw the T-v diagram for this process indicating the SATURATION CURVE, RELEVANT PRESSURE LINE(S), PROCESS PATH and LOCATIONS FOR SYSTEM STATES of interest.
