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…

You are the mechanical engineer supervising the layout of a piping system. In a certain portion of the pipe, the specifications are as follows: length of pipe is 10m, inside diameter of 30cm, outside diameter of 30.5cm, maximum allowable speed of 15m/s and a coefficient of 0.003456. If the uncertainties are 0.02mm for length, 0.8mm for the diameters and 0.1mm/s for the velocity, what loss of head will be imminent in this pipe?
