Q4.10) Figure 4.10 shows a flow-obstruction flowmeter with circular cross sections. The fluid is incompressible and has a constant density of p= 1250 kg/m3 when it goes through the flowmeter. The ratio of cross-sectional area A₁ to A2 is 3:1. The radius of Al is 0.04 m. The flow coefficient Kv is 0.95. The pressure difference is measured to be Ap = 300 Pa. A₁ Pi P2 Ap ↑42 A₂ P3=? I. Calculate the cross-sectional area of A1 and A2. II.Find the flow volume rate for the flowmeter. III. There is another pressure tap down-stream of the flowmeter; it is measuring p3, as shown in the diagram above. Arrange p1, p2 and p3 in increasing magnitude that is expected. (Note: there is no need to calculate the exact values of p1, p2 or p3, and their exact values are not needed to answer this question.) V. Briefly explain the answer in part (III). |

A cylindrical tank with a large diameter is filled with water to a depth D = 0.402 m. A hole of cross-sectional area A = 5.26 cm2 in the bottom of the tank allows water to drain out.

(b) At what distance below the bottom of the tank is the cross-sectional area of the stream equal to one-half the area of the hole?
Water flows through a pipe AB of diameter d1= 60mm, which is in series with a pipe BC of diameter d2= 85mm in which the mean velocity V2 = 3m/s. At C the pipe forks and one branch CD is of diameter d3 such that the mean velocity V3 is 2.5 m/s. The other branch CE is of diameter d4= 40mm and conditions are such that the discharge Q2 from BC divides so that Q4= ½ Q3. Determine Q1, Q3, Q4 and d3.
