A factory wants to fill A conical Storage tank with sand The tank has a height of 19.5

what kind of relationship is "h 20 100" ??

and what does "Qp h(t) Tank written:"

It's nice to try and provide context, but make sure it makes sense.

To get the answer, we need to know the dimensions of the conical storage tank, specifically its height and base radius. You mentioned that the tank has a height of 19.5, but we need the base radius to calculate the volume of the tank.

Could you please provide the base radius of the conical storage tank?

A storage tank has its top at ground level and is 10 meters deep with a volume of 10' m3. The tank is to be emptied with a pump having the following relationship between the head added by the pump and flow rate: h 20 100 where h is the head in meters and Qp is the flow rate in m's. The pump discharges at ground level and you should assume there is no head loss in the piping system. If the tank is initially full of water and there is no inflow to the tank, how long will it take to empty the tank? Qp h(t) Tank written: a. Show that the differential equation for the change in h with time i can be wrtten dh 2- at 100 10 b. Given that separating variables yields the following equation for femp, find p h=10 dh 1004 t-tempty dt
