7. When you work for a company that studies the performance of car engines, you are tasked with accurately measuring the amount of air intake by car engines. A gas flow meter was introduced from the United States to measure the amount of air. This flow meter measures the flow rate using the pressure difference. Looking at the instruction manual of this flow meter, the following equations were found for the pressure difference head and volume flow [unit, volume/time]. ▷ Volumetric Flow Rate[ft°/min]: =(55.3658* DP-0.143168* DP^ 2)) However, DP is the head (water height) of the manometer, and the unit is inch to be. In the above equation, if you insert DP[inch], the air volume flow rate can be calculated and the unit of the volume flow rate is ft/min. Complex unit conversion is included in the constant in front of DP, so you don't need to worry about it. Before the experiment to measure the amount of air inhaled into the engine, the current atmospheric pressure and temperature were 756mmHg and 25℃, respectively. After starting the engine test, the head of the liquid column was measured to be 38mm. Answer the following questions. However, the unit should be answered by the one suggested in the question. Treat air as an ideal gas, and if necessary, use the ideal gas state equation learned in physics. (1) What is the volumetric flow rate [m/min] of air entering the engine? (2) What is the mass flow rate [kg/min] of air entering the engine?
