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.
In the presence of electronic, ionic and dipolar polarization mechanisms, t he average induced dipole moment per molecule will be the sum of all the contributions in terms of the
What is the difference between the Atomic Theory and the Kinetic Theory? Atomic theory is all about structure of an atom, i.e., its composition. Like an atom in general is made
(Assume the metallic ball is spherical with a diameter d = 2.5 cm. Let''s also assume it is made out of nickel, which has a density of roughly 9 g/cm 3 .) After it first touches
Radio Waves: Radio waves are electromagnetic waves with large range of wavelength from a few millimetres to many meters.
When a certain beam of light falls upon a metal surface, it ejects photoelectrons from it. The number of photoelectrons ejected per second by the beam of light depends upon on
