An open tank contains ethylene glycol at 25°C. Compute the pressure at a depth of 3.0 m.
For the tank of ethylene glycol described in Problem 1, compute the pressure at a depth of 12.0 m.
Figure 3.19 shows a diagram of the hydraulic system for a vehicle lift. An air compressor maintains pressure above the oil in the reservoir. What must the air pressure be if the pressure at point A must be at least 180 psig?
