Can somebody show me the missing steps? Calculus statement soon to come...
\[\frac{ dh }{ dt }=\frac{ d({h^{1/2})}^2 }{ dt }=2h^{1/2}\frac{ d{h^{1/2}} }{ dt }\]
Please show how they go from (2) to (3)
There are initial conditions of t=0 and h=h* if that helps any
chain rule
h is height. This is a cylindrical tank problem.
\[\frac{d}{dx}[f^2(x)]=2f(x)f'(x)\]
why you would want to do this is not clear, but it is via the chain rule
that's right.. Thanks

Chemical Engineering question. I'll post the original question so you can satisfy your curiosity
A cylindrical tank with an inside radius R and is initially filled with water to a height h*. At time t = 0, a drain opening at the bottom of the pool is opened and water is drained from the pool at a volumetric rate v(out) given by v(out)=α'h^½, where h is the height of the water level in pool at time t, and α' are constants with the appropriate units. Derive and solve the differential equation governing h(t) in terms of the parameters given above.
@satellite73 I posted the question it your were curious why
