Water enters a 13-cm-diameter pipe steadily with a uniform velocity of 2 m/s and exits with the turbulent flow velocity distribution given by u = umax(1 − rR)1/7 . If the pressure drop along the pipe is 10 kPa, determine the viscous force exerted in the pipe by the water flow. Take the density of water to be 1000 kg/m3. The average velocity is equal to 0.816 times the max velocity. The viscous force exerted in the pipe by the water flow is 50

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
