a pipe a& b connecting two reservoirs is of 75 mm diameter (as shown in figure
qi). from a to b it is horizontal and from b to c it falls 3.3 m. the lengths of ab and
bc are 24 m and 15 m respectively and each length has two 90° bends in them. the
water level in the reservoir at a is 3.7 m above the pipe and at the level is 1 m
above the pipe. assume: the fanning friction factor, 0.006 and the entrance and
exit losses are 0.5(u/2g) and 1.0(up/29) respectively. the loss due to each of the
90° bends is 0.4(u®/29).
calculate:

a) the quantity which will flow through the pipe
b) the pressure at point b, commenting on its implications bv
c) the total flow rate needs to be increased by 18 m/hour by adding a second pipe
in parallel to the first. neglecting the minor losses (entrance, exit and bend losses),
calculate the minimum diameter of this new pipe. d. 50.3 minte
