There are several gas cylinders that are under pressure, which are located outside of the maintenance department. as the safety professional, you have been asked a couple of questions regarding this issue. provide the correct responses, and discuss your recommendations for any control measures.
the volume of the gas cylinder is 25.7 liters and exerts a pressure of 670 mmhg. if part of the gas is used, the pressure drops to 595 mmhg. what would be the remaining volume of gas?

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
