Realizar un programa con el lenguaje de bloques de funciones (FBD) y diagrama de contactos (ladder) de la imagen propuesta donde Km1 y Km2 son motores. El circuito consiste en el control de un contactor KM1 que es gobernado mediante una botonera de marcha-paro. este contactor activa un temporizador a la conexión, el cual transcurrido un tiempo prefijado activa un segundo contactor.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
