Question

22/// Calculate the power required to pump sulphuric ac id (dynamic viscosity 0.04 Pa⋅s, relative density 1.83 ) at 45 L⋅s−1 from a supply tank through a glass-lined 150 mm diameter pipe, 18 m long, into a storage tank. The liquid level in the storage tank is 6 m above that in the supply tank. For laminar flow f=16/ Re; for turbulent flow f=0.0014(1 +100Re−1/3 ) if Re<107. Take all losses into account. Take total k=1.5

Answer 1

To calculate the power required to pump sulphuric acid through the pipe, we need to consider the pressure difference and the flow rate.

Step-by-step explanation:

To calculate the power required to pump sulphuric acid through the pipe, we need to consider the pressure difference and the flow rate.

The pressure difference can be calculated using Bernoulli's equation, which states that the pressure at a point in a fluid is the sum of the pressure due to the height of the fluid column and the pressure due to the flow velocity.

The flow rate can be calculated using the equation Q = Av, where Q is the flow rate, A is the cross-sectional area of the pipe, and v is the velocity of the fluid.

Using the given information, we can calculate the pressure at the entrance of the pipe and then use that to calculate the power required using the equation P = QΔP.
