In a process plant, water is flowing through a globe valve. The pressure before the entering the globe valve is 10 bar and the velocity through a 100 mm valve inlet is 4 m/s. The valve is horizontally placed and when it is 50% open the downstream pressure is observed to be 2 bar. The outlet section of the valve has same diameter as the inlet section. Calculate the power needed to for water to flow through this valve. 4.28 kW 8.28 kW O 10.28 kW O None of the above 6.28 kW

Forms of Energy

Energy is described as the capability to accomplish a task, like the ability to push a block by applying force on it. It is a quantitative property that is used to accomplish work on an object.
