A U-shaped tube contains water (of density p=998 kg/m³) in its right arm, and an oil of unknown density px in its left arm. When the water and oil are in static equilibrium, the values of 1 and d, shown in the figure, are 1 = 135 mm and d=12.3 mm, respectively. Question 4: The pressure at the water-oil interface is A. px g(1+d) B. Pet g(l+d) A Option O Question 5: The value of p, is A. 915 kg/m³ Option B. 998 kg/m³ A O C. pw gl B O C.0 B O с Wa Ire D. None of the above O D. None of the above C D O

Tire gauges for air pressure, as well as most other gauges used in an industrial environment take into account the pressure due to the atmosphere of the Earth. That's why your car gauge reads 0 before you put it on your tire to check your pressure. This is called gauge pressure.   The real pressure within a tire or other object containing pressurized stuff would be a combination of what the gauge reads as well at the atmospheric pressure. If a gauge on a tire reads 13.55 psi, what is the real pressure in the tire in pascals? The atmospheric pressure is 1.01x105 Pa.

A tall, open container is full of glycerine. At what depth h below the surface of the glycerine is the pressure 2550 Pa greater than atmospheric pressure? The density of glycerine is 1.26 x 103 kg/m³. %3D
