A certain model of a car has gas-filled shock absorbers to make the car run smoother and less “bumpy.” Describe the gases inside the shock absorbers when the car is full of passen

Which of the following is true about components of a pneumatic system such as valves, pipes, and compressors? None of the these are true Undersized components such as pipes and valves do not influence pressure losses Air pressure losses in pipes do not influence the compressor required output pressure nor the input power Oversized components such as pipes and valves result in excessive initial installation costs Air leaks in pipe do not influence the flow rate required from the compressor

Utilize the formulae to determine the speed of sound and the number of Machs.

Is there a flaw in the pipeline design as shown in Flgure 4 ? (select one): (A) The strainer and foot valve should not be used as the combination may cause cavitation. (B) The foot valve should not be used as it may cause cavitation. (C) The pump should be placed at a higher elevation to prevent cavitation from occurring. (D) The gate valve should not be placed on the suction side of the pump as it may cause cavitation. (E) The intake is not placed deep enough below the water surface of the river as it may cause cavitation. (F) None Elevation 180 m- 450 All of Steel Pipe Diameter 250mm· Smooth Bend B Gate Valve- (wide open) River Elevation -Pump at Elevation 125 m 120 m Smooth Bend Sump -Strainer and foot valve at 115m Figure 4
