$[$Crowl $4-16]$ One accident mitigation procedure is called emergency material transfer, in which the material is transported away from the accident sit before it becomes involved. We plan on mitigating a crude oil tank fire scenario by pumping the tank empty in $1hr$ total time.

The crude oil tank is $30m$ in diameter, and the crude oil is typically at a level of $9m.$ The transfer will be accomplished by pumping the crude oil through a $200-mm$ ID new commercial steel pipe to another tank $40m$ in diameter and $10m$ high. The pipeline represents $50m$ equivalent of pipe. assuming pump efficiency of $80\%.$

b$)$ If a $100-$HP pump $(80\%$ efficient$)$ is available, how long will it take to empty the tank?

c$)$ What conclusions can be drawn about the viability of this approach?

Crude oil density: $928k\frac{g}{m^3}$

Crude oil viscosity: $0\mathrm{.}004k\frac{g}{m}s$
