Heptane flows through a reducer (Dinlet = 3-in Sch 40, Doutlet = 2-in Sch 40) at a rate of 1.5 gal/s. A mercury manometer is installed to measure the pressure difference. The specific gravity of heptane is 0.684. Calculate the velocity in the smaller diameter pipe. a. 1.84 ft/s b. 3.91 ft/s c. 5.76 ft/s d. 8.6 ft/s If frictional effects is neglected, determine the deflection of the manometric fluid. a. 0.15 in b. 0.35 in c. 0.58 in d. 0.72 in
