A rigid tank contains 10 kg of water at 90°C. If 8 kg of the water is in the liquid form and the rest is in the vapour form, determine the pressure in the tank.

Question

Quizplus · Accepted Answer

The pressure in the tank can be determined by looking at the saturation pressure of water at 90°C, since the tank contains both liquid and vapor phases of water, indicating that the water is at its saturation condition. At 90°C, the saturation pressure of water is approximately 70.183 kPa.
