## Fluid Mechanics For turbulent fluid flow in pipe, the expression for Prandtl one seventh power law is (where, r = pipe radius, x = distance).

None of these
V/Vmax = (r/x)1/7
V/Vmax = (x/r)1/7
V/Vmax = (x.r)1/7

## Fluid Mechanics In laminar flow through a round tube, the discharge varies

Linearly as the viscosity
Inversely as the viscosity
As the square of the radius
Inversely as the pressure drop

M & G coincide
M is above G
M is below G
None of these

## Fluid Mechanics The energy loss in flow through ven-turimeter is less than that through flow nozzle, because in case of a flow nozzle, the

Length is shorter
Sudden expansion of flow in the downstream occurs
Throat diameter is more
Distance between the throat and the inlet is more

## Fluid Mechanics Pressure drag does not depend upon the

Roughness of surface of the body
Pressure of main flow only
Length of the body in flow direction
All of these

## Fluid Mechanics In frictional fluid flow, the quantity, P/ρ + V²/2gc + gz/gc, is

None of these
Not constant along a streamline
Constant along a streamline
Increased in the direction of flow
