It is known that the pressure developed by a centrifugal pump, Δp, is a function of the diameter D of the impeller, the speed of rotation n, the discharge Q, and the fluid density ρ. Using the step-by-step method, determine the π-groups relating these variables.
An experimental program is being set up to calibrate a new flow meter. It is assumed that the mass flow rate is a function of the following variables: m= (ΔP, D, μ, ρ) where Δp is the pressure difference across the meter, D is the pipe diameter, μ is the fluid viscosity, and ρ is the fluid density. Using the exponent method, find the π-groups relating these variables.
What is the Interference ? A single frequency light passing through a pair of closely spaced slits will show a pattern of vertical bands, due to alternating constructive and des

The coherent & rationalized system of units, derived through the m.k.s. system (that itself is derived from the metric system) in common employ in physics today.
Sketch a graph showing the relationship among the magnetic field around a straight, current-carrying wire, and the distance from the wire. This is a graph of y = 1/x.
A medium is characterised by relative permittivity ε r =45 and relative permeability μ r =5. Determine the speed of e-m wave in the refractive and medium index of the medium.
