Question: A $35^{circ} mathrm{API}$ oil at $50^{circ} mathrm{F}$ is transported in a $2 mathrm{in}$. sch 40 pipeline. The oil flow rate is measured by an orifice

A $35^{\circ} \mathrm{API}$ oil at $50^{\circ} \mathrm{F}$ is transported in a $2 \mathrm{in}$. sch 40 pipeline. The oil flow rate is measured by an orifice meter that is $1.5 \mathrm{in}$. in diameter, using a water manometer.

(a) If the manometer reading is 1 in., what is the oil flow rate (in gpm)?

(b) If a venturi meter is used instead of the orifice meter, what should the diameter of the venturi throat be to give the same reading as the orifice meter at the same flow rate?

(c) Determine the unrecovered pressure loss for both the orifice and venturi meters.
