Water flows out of a reservoir, through a penstock, and then through a turbine. The mean velocity is 5.3 m/s. The friction factor is 0.02. The total penstock length is 30 m and the diameter is 0.3 m. There are three minor loss coefficients: 0.5 for the penstock entrance, 0.5 for the bends in the penstock, and 1.0 for the exit. Calculate the total head loss in units of meters.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed.gi) ifn 1, what will happen to the material when transformed material when
