1. Steam at a pressure of 2MPA and temperature 300°C is passed at a constant rate into a desuperheater unit. The desuperheater is accomplished by continuously spraying water at 95 °C onto incoming superheated steam. The amount of water injected is so regulated that both the water and superheated steam finally change into dry steam at 2 MPa. If the resulting mixture of dry saturated steam leaves the desuperheater at 2MPA and the rate of I kg/s, find the mass of superheated steam used per hour and the mass of water to be injected per hour. Fond also the diameter of the pipe through which the superheated steam flows to the superheater if the speed of the steam through the pipe is not to exceed 25m/s..
