Moist air at 27 deg c, 1atm, and 50% relative humidity enters an evaporative cooling unit operating at steady state consisiting of a heating section followed by a soaked pad evaporative cooler operating adiabatically. the air passing through the eating section is heated to 45 deg c. next, air passing through a soaked pad exiting with 50% relative humidity. using data from psychrometric chart, determine

a) the humidity ratio of the entering moist air mixture, in kg(vapor) per kg(dry air).
b) the rate of heat transfer to the moist air passing through the heating section, in kj per kg of mixture.
c) the humidity ratio and temperature, in deg c at the exit of the evaporative cooling section.

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?
