above the center of gravity.

below the center of buoyancy

above the center of buoyancy

between e.g. and center of pressure

velocity and pressure are inversely proportional

total energy is constant throughout

the energy is constant along a stream-line but may vary across streamlines

principle of conservation of mass holds

(ii) and (iii)

(i) and (iii)

(ii) and (iv)

(i) and (iv)

H3’2

H1/2

H5/2

H5’4 where H is head.

as the square of the radial distance

inversely as the square of the radial distance

inversely as the radial distance

linearly with radial distance

10.0 m above the hydraulic gradient

2.4 m above the hydraulic gradient

6.4 m above the hydraulic gradient

5.0 above the hydraulic gradient

Local atmospheric pressure depends upon elevation of locality only

A barometer reads the difference be-tween local and standard atmospheric pressure

Standard atmospheric pressure is the mean local atmospheric pressure a* sea level

Local atmospheric pressure is always below standard atmospheric pressure

head loss and discharge are same in two systems

length and diameter are same in two systems

friction factor and length are same in two systems

length of pipe and discharge are same in two systems

more

less

same

more or less depending on size of glass tube
