This document contains instructions for Assignment 4 in the MET212 Fluid Mechanics & Machines course. It includes 3 problems to solve: 1) Calculate the discharge rate through a Venturi meter given the pressure difference of 150 kPa and other provided data. 2) Calculate the force and work done per second on a flat plate impacted by a jet of water moving at 0.5 m/s at an angle of 60 degrees, given the jet radius and discharge rate. 3) Calculate the discharge of flow through a pipe connected to an open water tank, and determine the height needed to create a vacuum pressure of 30 kPa below atmospheric, given elevation changes, pipe lengths, and friction factor.

Assignment 4 MET212- Fluid Mechanics & Machines 2nd Semester, May 2012 Assignment # 4 Name…… ……… ……… …… ………… I.D No.…….… ……… Due date …at the class time late not accepted 10 (Submit as an individual work in a separate paper including this page as a cover page and keep your copy) 1.1 Calculate the discharge rate (Q) through the Venturi meter shown in Figure below with all data given and the ideal conditions are exists. Pressure difference between pipe and throat is 150 kPa. Ignore the head loss 1.2 A jet of water impact a flat plate with moving at u = 0.5 m/s in the same direction of the jet with angle of θ =60 degree. If the radius of the jet is 11 cm and the discharge is 0.1 m 3/s calculate the force, and the work done per second on the plate? 1.3 A Big tank of water open to atmospheric connected with pipe which has a constant diameter of 100 mm and exit to atmospheric. If the elevation different between point a and c = 5m (i.e. za-zc=5.0m), the length of the pipe between a and b (i.e. La-b= 6m) and the total length of the pipe is 20m.The friction factor = 0.09 A) Determine the discharge of the flow B) Determine the height of the pipe elevation above the surface of the tank to create vacuum pressure of (30 k Pa) below the atmospheric? assignment4-130115061159-phpapp01.docx4 Page 1 of 2
