Question

Fluid Mechanics - 1) state the meaning of this expression. 2) state the most general form of the local equation of conservation of mass, write the form in incompressible flow.

1. Fill in the missing letters in the expression that follows, where T represents temperature and subscripts M and S refer to material and spatial coordinates, respectivel;y State, in words, the meanng of this expression 2. State the most general form of the local equation of conservation of mass Write the form that expresses this principle for incompressible flow

Explanation / Answer

1)the value for filling the blank is x and t

this equatio shows the temperature distribution in transient heat transfer

2) general eqution for mass conservation in incompressible flow,

PAV=CONSTANT

WHERE P=DENSITY OF THE FLUID

A=CROSS SECTION AREA OF THE PIPE

V= VELOCITY OF THE FLUID
