awestion 3 (35 pts) water at Tjz1SC is heated in a chamber by mixing it with steam at paa300 kPaond TR320С The saturated liquid water and the steam enter the mibxing chamber through separate and independent inlet pipes. The saturated liquid water enters the mixing chamber at a rate of 3.0 kg/s, and the chamber loses heat to the surrounding air at 30 Cat a rate of 12 kW. The mixture leaves the mixing chamber...

1. (relative humidity) The partial pressure of water vapor in air is usually less than the equilibrium vapor pressure (or saturation pressure) at the ambient temperature; this is why a cup of water will spontaneously evaporate. The ratio of the partial pressure of water vapor to the equilibrium vapor pressure (at the same temperature) is called the relative humidity. Saturated air, at 100% relative humidity, would be in equilibrium with a cup of liquid water. The saturation pressure depends strongly...

2.(40 pts.) A mixing chamber is used to heat liquid water to a saturated vapor by adding superheated steam. The liquid water enters through Line 1 at 1 MPa, a temperature of 100 C and a mass flow rate of 2 kg/s. The superheated steam enters through Line 2 at 1 MPa and 400°C. The combined stream exits through Line 3 as a saturated vapor at 1 MPa. The chamber also receives 3 MW of heat transferred from an external...

65. In car racing, one advantage of mixing liquid nitrous oxide (N2 O) with air is that the boiling of the “nitrous” absorbs latent heat of vaporization and thus cools the air and ultimately the fuel-air mixture, allowing more fuel-air mixture to go into each cylinder. As a very rough look at this process, suppose 1.0 mol of nitrous oxide gas at its boiling point, −88 °C , is mixed with 4.0 mol of air (assumed diatomic) at 30 °C...
