Un sistema cerrado contiene mezcla de 1 kg de agua líquida y 3 kg de vapor en equilibrio a 1,5 MPa. Se transfiere calor al contenido hasta que alcanza la temperatura de 500°C, a presión constante. Determine: La temperatura del estado inicial.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
