Let A = Area of the orifice in m 2, d = Diameter of the orifice, m, h w = Head of water in m, C d = Coefficient of discharge for orifice, ρ a = Density of air in kg/m 3 under atmospheric conditions, and ρ w = Density of water in kg/m 3 = 1000kg/m 3.
{"Image DocumentName": "4. Volumetric efficiency:", "Image ImageDescription": "3. Specific output: It is defined as the brake output per unit of piston displacement and is given by: 4. Volumetric efficiency: It is defined as the ratio of actual volume of the charge drawn in, during the suction stroke to the swept volume of the piston. The average value of this efficiency is from 70 to 80% but in case of supercharged engine it may be more than 100%, if air at about atmospheric pressure is forced into the cylinder at a pressure greater than that of air surrounding the engine.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
