Property Tables. (a) 1 kg of nitrogen is stored in a container with a volume of 10 L at a temperature of 100 K. Determine the phase of nitrogen in the container and its pressure. (b) A 1.2 m' rigid tank contains steam at 150 °C. One third of the volume is in the liquid phase and the rest is in the vapor form. Determine the pressure and the quality of the saturated mixture. (c) 3 kg of a two-phase, liquid-vapor mixture of carbon dioxide exists at -50 °C in a 0.07 m. tank. Determine the quality of the mixture. (d) A tank of refrigerant R-134a has a temperature of 20 °C and a pressure of 8 bar. Determine its specific volume and specific internal energy.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
