Ratio of Inertial forces to drag forces is called which number?
Reynold's number
Vector in physical science terms?
A vector is a physical magnitude where not only a number is important, but also an associated direction. This is commonly used (for example) for velocity, acceleration, force, and many others.
Is a change that produces a new element a physical change?
No, it is a chemical change. ---------------------------------- Yes, it is a physical change because this change not involve a chemical reaction but a nuclear reaction followed by a change in the number of protons and neutrons.

Reynold's number
What is the Froude number at the beginning of the jump if sequent depth ratio of a hydraulic jump in a rectangular channel is 16.48?
12
What is critical flow and sub critical flow of fluids?
Critical flow is the special case where the froude number (dimensionless) is equal to 1. i.e. The velocity divided by the square root of (gravitational constant multiplied by the depth) =1. Sub critical flow i has a froude number less than 1, and is therefore characterised by slow moving deep water. Supercritical flow is defined as having a froude number greater than 1 and is therefore characterised by shallow fast moving flows.
What values of froude number mean?
It is a dimensionless number that relates inertial to gravitational forces in the upstream flow. It is useful when looking at hydraulic jump (fluid dynamics)

How do you calculate kwh per square foot?
-- Write down the number of kwh -- Write down the number of square feet -- Divide the first number by the second number. -- The answer is mathematically correct, but doesn't appear to have any physical significance in the real world.
