Name the principle used to check the correctness of an equation.

in a particular experiment Ramu use the relation F=AB+(P+Q)Y to calculate force. which principle is used to check the correctness of the equation.

A company manufacturing PVC pipes claims in an advertisement that the volume of water flowing out through the pipe in a given time is as per the equation V=KA^2ut where A is the area of cross section of the pipe, u is the speed of flow, t is the time and K is a dimensionless constant. Name the principle that can be used to check the dimensional correctness of this equation.

A stone is thrown upwards from the ground with a velocity, u . a)What is the maximum height attained by the stone? b)Check the correctness of the equation obtained in,(a)using the method of dimensional analysis. c)Draw the position-time graph of the stone during its return journey

A stone is thrown upwards from the ground with a velocity u . What is the maximum height attained by the ball? Check the correctness of the equation thus obtained using the method of dimensional analysis.

"Velocity cannot be added to temperature" check the dimensional correctness of the equation PV=Fx where P is the pressure V is the volume F is force and x is displacement
