square inch absolute). 33.What is vacuum pressure? Gauges that indicate gauge pressure may be designed to indicate pressures below zero. Such a gauge is called vacuum gauge. Gauges that indicate absolute pressure cannot indicate pressure zero psi, because zero is a perfect vacuum. 34.What is static pressure? when the is in equilibrium, the pressure at a particular point is identical in all directions and independent of orientation. This is called static pressure. 35.What is velocity pressure? Velocity pressure is the difference between the total pressure and static pressure. VELOCITY PRESSURE=TOTAL PRESSURE-STATIC PRESSURE 36.What is the principle of c type-bourdon type pressure Principle: c type bourdon tube pressure gauge is works on the principle of Elasticity. 37. How to avoid barometric effect? Barometric effect occurs due to change in atmospheric pressure. This error can be avoided by keeping the filled system at a pressure sufficiently larger than the atmospheric pressure. 38.What are the different methods of temperature measurement? Bimetallic thermometers Liquid in glass thermometers Liquid in metal thermometers Gas thermometers Vapor pressure thermometers Mercury filled thermometers
