Hydraulics and Fluid Mechanics in ME When the pressure intensity at a point is more than the local atmospheric pressure, then the difference of these two pressures is called Vacuum pressure Gauge pressure Positive gauge pressure Absolute pressure Vacuum pressure Gauge pressure Positive gauge pressure Absolute pressure ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME The discharge through a small rectangular orifice is given by (where Cd = Coefficient of discharge for the orifice, a = Cross-sectional area of the orifice, h = Height of the liquid above the centre of the orifice) Q = (3Cd × a)/√(2h) Q = (2/3). Cd × a × h Q = (Cd × a)/√(2gh) Q = Cd × a × 2gh Q = (3Cd × a)/√(2h) Q = (2/3). Cd × a × h Q = (Cd × a)/√(2gh) Q = Cd × a × 2gh ANSWER DOWNLOAD EXAMIANS APP
