The gauge indicates oil pressure by a sensor directly connected to the engine lubrication system. Normal oil pressure is 30 to 70 psi (210 to 480 kPa) when the engine is at nor mal operating temperature. At idle speed, the pressure may drop to 5 to 20 psi (35 to 140 kPa). When first starting a cold engine, oil pressure may exceed 90 psi (620 kPa).

Pressure Problem using a Manometer? Yahoo Answers

  Best Answer: Using Pascals principle: Look it up if you don't know it. The pressure head measured by the mercury part of the manometer is L3 in feet. Note that the atmosphere is added to that. Thus L1 + L2 + air pressure in tank = L3 + atmospheric pressure. Use rho (density = 845lb/ft^3) of mercury to determine the pressure of that head.

Pressure

PRESSURE CONCEPT. Pressure is the ratio of force to the surface area over which it is exerted. Though solids exert pressure, the most interesting examples of pressure involve fluids — that is, gases and liquids — and in particular water and air. Pressure plays a number of important roles in daily life, among them its function in the operation of pumps and hydraulic presses.
