Hydraulics and Fluid Mechanics in ME A liquid would wet the solid, if adhesion forces as compared to cohesion forces are equal less more less at low temperature and more at high temperature equal less more less at low temperature and more at high temperature 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
