Oil, with a density of ρ = 900 kg m=3 and a kinematic viscosity of v = 0.1 m^2 s^-1, flows at a volume flow rate of q 0.2 m^3 s^-1 through 500 m of 200 mm diameter pipe which has a roughness of 0.26 mm. the chart for the fanning friction factor is given on p.8. determine: (i) the head loss if the pipe is installed horizontally and (ii) the pressure drop if the pipe slopes down at angle 10° in the flow direction from the horizontally installed position in (i).

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
