Given a ventilation rate of 500,000cfm, how much energy (in BTU/hr) will it take to heat the airentering the room if for each of the following recirculation rates?The specific heat for air is 0.0175 BTU per cubic feet of air perdegree Fahrenheit. The outside air temperature is 10°F and the airmust be heated to 90°F before it enters the room. Express youranswer to the nearest whole number.
Energy(BTU/hr) = Ventilation rate (ft3/hr) * Specific Heat(BTU/(ft3 °F) * Temperature Change (°F)
a. 20% recirculation.(3 points)
