An unknown ideal gas at 53 deg F and 3.3 in Hg (gauge) is flowing through an irregular duct. To determine the flow rate of the gas, carbon dioxide, from a modular carbon dioxide tank, is passed into the gas stream. The gas analyzes 1.2% CO2 before and 3.4% after addition. The tank is on a scale and found to lose 12 lb in 10 minutes; What is the flow rate of the ideal gas in ft^3/minute?
Evaporative cooling PLEASE DO NOT USE PSYCHROMETRIC CHART. THANK YOU In the diagram below inlet air is drawn over a pool of liquid water in a steady-state, steady-flow isobaric process. Evaporation on the pool resultsin saturated air at the exit. The pool of liquid water is assumed to be at the same temperature as the exitair. Discharge fans at the exit provide a volumetric flow rate of 800,000 ft3/min. In the diagram above inlet air is drawn over a pool of liquid water in a steady-state, steady-flow isobaric process.

Pls. Answer thank you! An auditorium is designed to seat 4500 people. The ventilation rate is 1.62×107 ft³/hr of outside air. The outside temperature is 0°F dry bulb, and outside pressure is 14.6 psia. Air leaves the auditotium at 70°F dry bulb. There is no recirculation. The furnace has a capacity of 1,250,000 Btu/hr. The temperature at which the air should enter the auditorium is most nearly?
