Determine the initial quality and temperature of the fluid, Ask an Expert

Academics

A piston-cylinder device contains a saturated mixture of steam and water having a total mass of 0.5 kg at a pressure of 160 kPa and an initial volume of 100 liters. Heat is then added and the fluid expands at constant pressure until it reaches a saturated vapor state. a) Determine the initial quality and temperature of the fluid mixture prior to heating. [quality x1 = 0.182, T1 = 113.3°C] b) Determine the final volume of the steam after heating. [0.546 m3 (546 liters)] Note: 1000 liters - 1 m3.
