Question

A 150-m-long commercial steel pipe is to convey 30 L/s of oil
(s = 0.9, p = 0.038 N-s/m) from one tank to another
(submerged discharge) where the difference in elevation of
the free liquid surfaces is 2 m (Fig. P8.69). The pipe
entrance is flush, and there is a fully-open gate valve in the
line. Using only a basic scientific calculator, find the
diameter theoretically required. (Hint: It may be easier to
try for D than for f in this case.)
A basic scientific calculator is here defined to be one that is not programmable and does not have
automatic equation solving capabilities.
