Law of flow
WebWe get R squared is equal to 32,000 divided by 15 rho-- rho is 1,000, so R squared is equal to 32,000 over 15,000, which is the same thing is 32 over 15. R is equal to the square root of 32 over 15, and that's going to be meters cubed per second. I get 32 divided by 15 is … WebIn fluid mechanics it is not clear what mass of moving fluid we should use so we use a different form of the equation. Newton’s 2ndLaw can be written: The Rate of change of momentum of a body is equal to the resultant force acting on the body, and takes …
