- Example (1-6): A pumping plant forces water through a 600 mm diameter main, the friction head being 27 m. In order to reduce the power consumption, it is proposed to lay another main of appropriate diameter along the side of the existing one, so that the two pipes may work in parallel for the entire length and reduce the friction head to 9.6 m only. Find the diameter of the new main if with the exception of diameter, it is similar to the existing one in every respect.arrow_forwardA single cylinder marine engine has a compression ratio () of 6.75, a clearance volume of 1200 cm3 and a piston stroke length of 500 mm.

The coefficient of friction between the engine and the rails is 0,1.

Based on where the water is hitting the ground, calculate what the water velocity is coming out of the hose for the different heights. First write a general equation for the water velocity based. on d and h, and then solve for it for the different hose heights shown in the pictures. Hint: The water path behaves like that of any other object thrown through the air. You may want to review projectile motion equations from PHYS 111. Data point 1: the lowest…arrow_forward

A duct of 0.45 m diameter and 90 m long leads from a fan discharge chamber where the pressure is 15 mm of water to a plenum chamber where the pressure is 10 mm of water. In order to increase the flow, two alternatives are considered. One is to lay a duct of 0.3 m diameter and 90 m long in parallel with the duct of 0.45 m diameter. The other is to increase the diameter of 0.45 m diameter duct for the last 60 m length. Calculate the increased diameter so that this method gives the same flow as the 0.45 m and 0.3 m ducts in parallel. Assume that the pressures in the fan chamber and plenum chamber are unaffected by changes in the flow and consider duct friction losses only. The friction factor may be taken as 0.0o55. 6. A 0.3 m diameter circular duct carries standard air at a velocity of 360 m/min. It is replaced by a rectangular duct having the same pressure loss per unit length due to friction. Determine the dimensions of the rectangular duct if the aspect ratio is to be 1.5 for (a)…arrow_forward
