22.
For a laminar flow of fluid in a circular tube, 'h1' is the convective heat transfer co-efficient at velocity 'V1'. If the velocity is reduced by half and assuming the fluid properties are constant, the new convective heat transfer co-efficient is
1.26 h1
0.794 h1
0.574 h1
1.741 h1

For laminar flow in tubes.

Nu=1.86*((Re*Pr)d/L)0.33.

0.33 is power.
