An unstretchable cable with mass per unit length 5 kg/m is hanging between points A and B. The horizontal distance between A and B is 20 m. The vertical distance is 15 m (B is in a lower position). We measure a point on the cable which lies by a horizontal distance of 5 meters to point A. It is found to be 4 meters lower than point A. The shape of the cable is almost straight.Use the small sag approximation (Lecture 5) and keep the accuracy to O (e) to estimate the horizontal load H on A and B.

At sections 1 and 2, the flow is uniform and the pressure is hydrostatic. Neglecting bottom friction and atmospheric pressure, calculate the velocities V1 and V2, and the horizontal force, F, required to hold the gate if h1 = 6m, h2 = 1m, and b = 5m. h₁V₁ Sluice gate, width b Farrow_forwardQuestion 1 A pipeline 30 m long connects two tanks which have a difference of water level of 12 m. The first 10 m of pipeline from the upper tank is of 40 mm diameter and the next 20 m is of 60 mm diameter. At the change of section, a valve is fitted. Calculate the rate of flow when the valve is fully opened assuming that its resistance is negligible and that f for both pipes is 0.0054. In order to restrict the flow the valve is then partially closed. If k for the valve is now 5.6, find the percentage reduction in flow.
