Water vapor has a quality of 90% at 200°C. Determine the enthalpy and specific volume.

Three kilograms of water in a vessel has a pressure of 100 kPa and a temperature of 150°C. What is the volume of this vessel?

Complete the following table for water (H2O)

A tank with a volume of 0.5 m3 contains a mixture of steam and water at 300°C. Determine (a) the mass of each phase if the volumes are the same and (b) the volume of each phase if the masses are the same.

A strong tank with a size of 1.8 m3 contains steam at a temperature of 220°C. One-third of the volume is in the liquid phase and the rest is in the vapor form. Determine (a) the vapor pressure, (b) the quality of the saturated mixture, and (c) the density of the mixture.

Water will be boiled at sea level in a stainless steel pot with a diameter of 30 cm placed on a 3 kW electric stove. If 60 percent of the heat produced by the burner is transferred to the water during boiling, determine the rate of water evaporation.

A strong tank of 1.5 m3 contains 2.5 kg of water at 200 kPa. Determine (a) the temperature, (b) total enthalpy, and (c) the mass of each phase.
