Question
An anchored barge that extends across a canal by distance d = 30 m and into the water by distance b = 12 m. The canal has a width D = 57 m, a water depth H = 14 m, and a uniform water-flow speed vi = 1.3 m/s. suppose that the flow around the barge is uniform. As the water passes the bow, the water level undergoes a dramatic dip called the canal effect. If the dip has depth h = 0.75 m, what is water speed along the boat during the vertical cross sections at
(a) Point a and
(b) Point b?
The erosion due to the speed enhance is a common concern to hydraulic engineers. Also, the dip is at point a. And point b is on surface of water.
A large storage tank, open to the atmosphere at the top and filled with water, Determine the speed at which the water leaves the hole
A windmill has an initial angular momentum of 8270 kg · m2/s. The wind picks up, and 5.81 s later the windmill's angular momentum is 9310 kg · m2/s
A charge of -7.1 micro-Coulombs is placed at x = 0, y = 0. A charge of +18.7 micro-Coulombs is placed at x = 0, y = +30 cm. Another charge of +31.3 micro-Coulombs is placed at x = +31 cm, y = 0 cm.

Two point charges lie along the y axis. A charge of q1 = -12.0 µC is at y = 7.0 m, find the point at which the total electric field is zero
A cup of water is heated with a heating coil that delivers 27.28W of heat. What is the mass of the water
Nitrogen and oxygen in their liquid states have densities only 0.80 and 0.90 that of water. Atmospheric pressure is due primarily to weight of nitrogen and oxygen gas in the air. If atmosphere liquefied would its depth be greater or less than 10.30 m..
