The visitor center at Zion National Park uses evaporativecooling towers to condition the inside air. During the day, thecenter receives heat from the environment through conduction,convection, and radiation. In order to maintain a constanttemperature that heat must be removed. Evaporation of water in thecenter\'s cooling towers removes heat so the air conditioning systemdoesn\'t have to, which reduces energy usage and cost.

a. If the visitor center receives average of45 MJ each hour of heat from theenvironment, estimate the mass of water would need to be evaporatedeach hour in order to counter-balance all the incoming heat.Answer: kg per hour. round to nearestwhole number

b. How many liters per hour of water would that be? Answer in L
