An air dryer is used to dry wet coal at a rate of 10,000 tons per day. Wet coal feed has 24 percent by mass of water when it enters and 4 percent when it exits. The hot air used to dry the wet coal is heated to 40°C for the dry bulb and 16°C for the wet bulb. At 30°C, the moist air exits the dryer with a relative humidity of 40%. Calculate the dry amount of air in m3/h at STP. (Use psychrometric chart)

The sensible heat-transfer coefficient for a dry surface has been determined to be 50 W/(m2-C) at a certain Reynolds number. Estimate the total heat transfer to the surface per unit area at a location where the wall temperature is 10 C and the state of the moist air flowing over the surface is given by 24 C dry bulb and 18 C wet bulb. Assume that the Reynolds number does not change and the Lewis number is 0.82. Assume that the condensate present on the surface will increase the transfer coefficients by about 15 percent.

the latent heat of vaporization is about 2.44 x 10⁶ J/kg and the density (density) of the vapor is 0.598 kg/m³ at 100 °C per km. Determine the rate of change of the boiling point with altitude approaching sea level in °C per km. It is known that the density of air at 0°C and 1 atm is 1.29 kg/m and the density of water is 1000 kg/m³. Assume the air temperature is 300°K. The change in pressure with altitude is given by the relationship P(z) = P(0)exp - (mgz)/(kT)
