You have been asked by your boss to select a flow meter to measure the flow rate of gasoline $(\mathrm{SG}=0.85)$ at $70^{\circ} \mathrm{F}$ in a 3 in. sch 40 pipeline. The maximum expected flow rate is $200 \mathrm{gpm}$, and you have a DP cell (which measures differential pressure) with a range of $0-10$ in. $\mathrm{H}_{2} \mathrm{O}$ available.

(a) If you use a venturi meter, what should the diameter of the throat be?

(b) If you use an orifice meter, what diameter orifice should you use?(c) For a venturi meter with a throat diameter of 2.5 in., what would the DP cell read (in inches of water) for a flow rate of $150 \mathrm{gpm}$

(d) For an orifice meter with a diameter of 2.5 in., what would the DP cell read (in inches of water) for a flow rate of $150 \mathrm{gpm}$.

(e) How much power (in hp) is consumed by friction loss in each of the meters under the conditions of (c) and (d)?
