Hydraulics and Fluid Mechanics in ME Reciprocating pumps are no more to be seen in industrial applications (in comparison to centrifugal pumps) because of Lower speed of operation High initial and maintenance cost Necessity of air vessel Lower discharge Lower speed of operation High initial and maintenance cost Necessity of air vessel Lower discharge ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME An open tank containing liquid is made to move from rest with a uniform acceleration. The angle 0 which the free surface of liquid makes with the horizontal is such that (where a = Horizontal acceleration of the tank, and g = Acceleration due to gravity) tanθ = a/g tanθ = a2/2g tanθ = 2 a/g tanθ = a/2g tanθ = a/g tanθ = a2/2g tanθ = 2 a/g tanθ = a/2g ANSWER DOWNLOAD EXAMIANS APP
