It is sometimes necessary to produce saturated steam from superheated steam. This change can be accomplished in a desuperheater, a device in which just the right amount of water is spayed into superheated steam to produce dry saturated steam. If superheated steam at 3 MPa and 500oC enters the desuperheater at a rate of 500 kg/hr, at what rate should liquid water at 2.5 MPa and 25oC be added to the desuperheater to produce saturated steam at 2.25 MPa?
