Example 1 A reservoir of water is connected to a pipe, as shown in the figure. The pipe valve
is closed, preventing any flow. Find the water pressure in the center of the pipe at
the valve. The elevation of the reservoir surface is 550 m and that of the center of
the valve is 525 m
Elev. 550.0
Closed valve
Elev. 525.0

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

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
