QUESTION: 1

Two reservoirs at different levels are connected by two parallel pipes of diameter '2d' and 'd'. The ratio of the flows in the two pipes (larger: smaller) is

Solution:

⇒

QUESTION: 2

A 15 cm diameter pipe carries a flow of 70 L/s of an oil (RD = 0.75). At a section 12 cm above the datum the pressure is vacuum of 2 cm of mercury, if the kinetic energy correction factor a for this section is 1.1, the total head at the section in metres of oil is

Solution:

The loss of head due to friction in a pipe of uniform diameter in which viscous flow is taking place is

where R_{e} = flow Reynold’s number

Solution:

QUESTION: 4

In the Moody diagram the third parameter is k_{s}/D. Here k_{s} is

Solution:

QUESTION: 5

A compound pipe of diameters d_{1}, d_{2} and d_{3} having length l_{1}, l_{2} and l_{3} respectively, is to be replaced by an equivalent pipe of uniform diameter d and length l. The size of the equivalent pipe is given by
