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 = a/2g tanθ = a2/2g tanθ = 2 a/g tanθ = a/g tanθ = a/2g tanθ = a2/2g tanθ = 2 a/g ANSWER DOWNLOAD EXAMIANS APP
