. A pump draws water from a reservoir and conveys it to another reservoir 30 m above. The sucLon pipe is 100 mm in diameter and 10 m long while the delivery pipe is 100 mm in diameter and 150 m long. if the velocity in the pipe is 3 m/s, the fricLon factor of the pipe 0.008, and the pump and motor efficiencies 85 % and 92 %, respecLvely. See Figure Q6.1. Calculate:(a) Gauge pressure at the pump's inlet (at C) (10)(b) Gauge Pressure at the pump's outlet (at D) (10)(c) input power to motor (5)

0.12 O -0.12 8.33 (1) Darcy Experiment A set-up of Darcy Experiment involves measuring the pressure head at two piezometers separated a distance, L. Given the set-up shown, determine the hydraulic gradient if the hydraulic head at (1) is 66 cm, hydraulic head at (2) is 54 cm, and the travel distance is 100 cm. O-8.33 -L h e - - - -

As shown in the figure below, a Venturi meter is installed on a 300-mm diameter pipe whose maximum flow is 125 liters per second and the pressure head is 6.5 m of water. Determine the minimum throat diameter that will give a negative head. Solve for the discharge that will pass through the meter when the double column differential mercury gauge connected to it will show a difference of 25 cm. |25сm P. 36.5 h A2 300mmф Al ANSWER: a. D = 118mm b. Q = 87 liters/sec

Could I get a written solution for this question please?

I need a quick solution within 15 minutes With my best wishesTon.

Fluid mechanis Read the question carefully, give me right solution The head loss (hf) in a 1200mm x 600mm pipe (therefore, non-circular) conveying water is estimated to be 0.04m for every 1 meter of its total length. If the said pipe is filled with water and its friction factor f = 0.032, what should be the discharge Q?

NEED COMPLETE SOLUTION. NEED ASAP. Thnak you

Thank you expert !!
