A pipe difference cross sections (2.2, 25.8, 6.5) cm^2 respect at points (1, 2, 3) the height of these points 92, 65, 21 cm based to the reference line. The pipe join to an open tank height of the water in the tank is 2 m base to the reference line. Calculate:
i/ Q?
ii/P & V at all points?
Ans. (Q=3.84*10^-3 m^3/sec)
