Convection is transfer of heat between a solid and a moving fluid. Boiling or condensing processes are example for convection processes.
The formula for convection is:
<span>q = hc A dT</span>
where
<span>hc is convective heat transfer coefficient of the process (W/(m2K) or W/(m2oC <span>q
</span>A<span> is the heat transfer area of the surface (m2, ft2)
</span><span>hc </span><span>= convective heat transfer coefficient of the process (W/(m2K) or W/(m2oC), <span>Btu/(ft2 h oF)</span>)</span><span>q is heat transferred per unit time (W, Btu/hr)</span>dT is the <span>temperature difference between the surface and the bulk fluid (K or oC, F)</span>

Answer:
Explanation:
mass of the water being lifted per second
m = volume x density
= 6.2 x 1 = 6.2 kg
height by which water being lifted
h = 75 - 21
= 54 m
increase in potential energy of water per second
mgh
6.2 x 9.8 x 54
= 3281.04 J /s
= 3281.04 W.
<em>velocity over time I think</em>
