ExamplesFor incompressible fluid (not flow) density isconstant, hence V 1 A 1 = V 2 A 2• Example 3-12 – This is a simple probleminvolving a constant flow rate through a gardenhose nozzle.• Example 3-13 – This is an interesting example tocompute discharge time for water in a tank.Note that the discharge velocity is a function ofthe level of water in the tank which falls withtime as water is discharged. Clearly this is aproblem of mass conservation in rate form, i.e. itis a unsteady state problem. Pls review carefully.Energy Transfer 45© Copyright 2005 Prof. Arun S. Mujumdar.
