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.

Q. Why does heat makes matter to expand? Answer:- Water contracts as it cools similar to all other liquids until it reaches a temperature of about 4 degrees Celsius at whi
State the Working of UJT Make circuit arrangement as demonstrated in fig.(c), where UJT is represented by its equivalent circuit comprising resistances R B1
3 scenarios: You have an object such as a jar, and you submerge it under water to 50m depth. (Every 10m down increases pressure by 1 bar, thus the pressure is 5 bar). Scenario 1:
A 10L helium balloon at a pressure of 2 bar at 27C. some O 2 is now in balloon and final volume is made 30L. the pressure also fell to 1 bar at same temperature. the partial press
