Assume that the head loss in the pipes is given by hL = 0.02(L/D)(V2/2g), where V is the mean velocity in the pipe, D is the pipe diameter, and L is the pipe length. The water surface elevations of the upper and lower reservoirs are 100 m and 60 m, respectively. The respective dimensions for upstream and downstream pipes are Du = 32 cm, Lu = 190 m, Dd = 12 cm, and Ld = 110 m. Determine the discharge...
For flow in a pipe of uniform diameter D the loss in hydraulic head, h, is given by: L u2 D 2 where L is the length of the pipe, u is the average flow velocity, g is the acceleration due to gravity and f is a constant. During reconfiguration of a plant it is estimated that the length of the pipe could be reduced by 15% and its diameter increased by 6%. Calculate the maximum percentage by which The...
The hydraulic head loss in a pipe may be determined by the Darcy-Weisbach Equation as follows: H=(f*L*V^2)/(2*D*g) Where L is the length of the pipe, V is the follow velocity of water in a pipe, D is the pipe diameter, f is the coefficient of friction and g is the gravitational acceleration (32.2 ft/sec^2) Suppose the length of the pipe L has a constant length of 10 ft and the pipe has a constant diameter of .5 ft. The coefficient...
Open with Google Docs ▼ Question 3 Calculate the flow rate of water in a pipe of 30 cm diameter placed in an inclined position where a venturi meter is inserted, having a throat diameter of 15 cm. The difference of pressure between the main and throat is measured by a liquid of s.g. 0.6 in an inverted U-tube which gives a reading of 30 cm. The loss of head between the main and throat is 0.2 times the kinetic...
A flow nozzle equipped with a differential pressure gage is used to measure the flow rate of water at 10°C (p 9997 kg/m3 and p 1.307 x 10-3 kg/m s) through a 3-cm-diameter horizontal pipe.
