A pump supplies 40 L/min of water through 30 m of 2.54 cm galvanized pipe. The pipe has one fully open globe valve and two 90o standard elbows. Water is delivered at 140 kPa to a tank located 15 m above the pump intake. What is the pump motor power requirement if the combined pump and motor efficiency is 0.70? Assume the temperature of the water is at 20oC with kinematic viscosity and absolute viscosity at 1.006×10-6 m2/s and 0.9934×10-3 Ns/m2, respectively

On a average work day more than work place firs are reorted

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
