Water flows steadily from an open tank as represented in the diagram below. The elevation (from ground level) of point A is 10.0 m, and the elevation of points B and Cis 2.0 m. The cross-sectional area of the pipe at point B is 0.0480 m² and at point C is 0.0160 m2. The area of the tank is very large compared with the cross-sectional area of the pipe. Considering water and incompressible fluid, find: a) The discharge rate (flow) in cubic meters per second. b) The pressure at point B.

7.11.* A nozzle is bolted onto a pipe by the flanged joint shown in Fig. 7.29. The flowing fluid is water. The cross- sectional area perpendicular to the flow at point 1 is 12 in² and at point 2 is 3 in². At point 2 the flow is open to the atmosphere. The pressure at point 1 ≈ 40 psig. (a) Estimate the velocity and mass flow rate by B.E. (b) What is the force tending to tear the nozzle off the pipe? Water Pipe #O FIGURE 7.29 Nozzle, bolted to pipe. Nozzle

2. Here's an interesting one. Consider a sled .. a rocket cart which is used to study acceleration and deceleration effects. (Yes that's a real thing). One way of stopping such a sled is to put a scoop on the front deflecting water upwards as in the image below: Water 60⁰ Assume scoop is 20 cm wide (into page), and dips 8 cm into the water (d = 8 cm). The sled is 1000 kg and initially traveling at 100 m/s. What is the initial deceleration .. remember F = ma.

please solve b and shows the steps
