The trapezoidal channel is made of brickwork n 0.015 with a side slope 1: 2 and longitudinal slope of 0.002 (m/m). 1)-determine the flow rate if the normal depth is 80cm 2)- what is the regime of the flow. 3)-calculate the critical depth. 4)-explain your result using the energy diagram for open channel.

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.
