Alake with an area of 525 [acre] was monitored during a one-month period. the average inflow was 30 [cfs] for the month and the average outflow was 27 [cfs]. a 1.5 [inch] seepage loss was measured and there was 4.25 [inch] of rain. evaporation was measured as 6 [inch]. calculate the change in lake storage for the month.

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.
