Dimensional homogeneity

The term dimensional homogeneity means that in an equation, the dimensions of each term on both sides are equal, which means the dimensions of the left-hand side (LHS) of an equation are similar to the dimensions of the right-hand side (RHS). For a dimensionally homogeneous equation, the powers of fundamental dimensions will be identical on both sides of the equation.

A 7350 m long, 1050 mm concrete pipeline connects an upstream reservoir (watersurface elevation 433.3 m) to a downstream reservoir (water surface elevation 423.1 m). Adischarge valve at the downstream end is used to control flow; when this valve is fully open,the measured discharge in the pipeline is 920 L/s under the naturally available head difference.(a) Assuming fully developed turbulent flow and that all other local losses are negligible,estimate the loss coefficient k for the fully open valve (assume f = 0.015).(b) Because of increasing urban development, the flow under the natural head difference isconsidered to be inadequate and it is proposed to increase this flow with pumping. The head-capacity curve for the pump can be approximated by the equation H = 8 – 3.5Q2 in which H isthe total dynamic head on the pump (in m) and Q is the discharge (in m3/s). What is thedischarge that can now be obtained from the system where the pump is installed at a cross-section of the pipeline?
