Fluid Mechanics With the increase in depth, the hydrostatic pressure in an unaccelerated incompressible fluid (in a constant gravitational field) Increases exponentially Decreases Increases linearly Remains constant Increases exponentially Decreases Increases linearly Remains constant ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics Two fluids are flowing through two similar pipes of the same diameter. The Reynold's number is same. For the same flow rate if the viscosity of a fluid is reduced to half the value of the first fluid, the pressure drop will Data insufficient to predict relative pressure drop Remain unchanged Increase Decrease Data insufficient to predict relative pressure drop Remain unchanged Increase Decrease ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics Water hammer is caused, when water flowing in a pipe is suddenly brought to rest by closing the valve. The extent of pressure thus produced due to water hammer depends on the Fluid velocity in the pipe All of these Time taken to close the valve Pipe length Fluid velocity in the pipe All of these Time taken to close the valve Pipe length ANSWER DOWNLOAD EXAMIANS APP
