Se desea evaporar cien moles por hora de etanol a 25°C y 3 atm, calentándolo hasta 300 ° C a presión constante. Para esto se utiliza vapor de agua sobrecalentado en un intercambiador de tubos concéntricos. [30] a. Diagrama T-h para el etanol a una atmosfera y 3 atmosferas. [10] b. Velocidad a la que debe suministrarse calor al proceso kJ/h

Atmospheric air has a temperature (dry bulb) of 80° f and a wet bulb temperature of 60° f when the barometric pressure is 14.696 psia. determine the specific humidity, grains/lb dry air. a. 11.4 c. 55.8 d. 22.5 b. 44.1

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.

The proportional limit is always greater than the yield strength for a material. a)-trune b)- false
