The pressure head drop across a short section of an $8-$in$.-$pipeline $($PVC$)$ is $12ft.$ The pipeline section contains a globe valve and another valve of some kind that is open but not labeled. Determine what kind of valve it is if the flow rate is $2\mathrm{.}74f\frac{t^3}{s}.$ Assume that the friction loss is negligible in the short pipe segment.
