A brine solution with a density of 1230 kg/m3 movesthrough a constricted pipe in steady, ideal flow. At the lowerpoint shown in the figure below, the pressure isP1 = 2.00 ✕ 104 Pa, and thepipe diameter is 7.00 cm. At another point y =0.40 m higher, the pressure is P2 =1.25 ✕ 104 Pa and the pipe diameter is 3.50 cm.
(a) Find the speed of flow (in m/s) in the lower section.
(b) Find the speed of flow (in m/s) in the upper section.
(c) Find the volume flow rate (in m3/s) through thepipe.
