Applying Conservation of MassLiquid water flows
Chapter 4, Problem 8P(choose chapter or problem)
Liquid water flows isothermally at \(20^{\circ} \mathrm{C}\) through a one inlet, one-exit duct operating at steady state. The duct's inlet and exit diameters are \(0.02 \mathrm{~m}\) and \(0.04 \mathrm{~m}\), respectively. At the inlet, the velocity is \(40 \mathrm{~m} / \mathrm{s}\) and pressure is 1 bar. At the exit, determine the mass flow rate, in \(\mathrm{kg} / \mathrm{s}\), and velocity, in \(\mathrm{m} / \mathrm{s}\).

ANSWER:Solution 8P
Step 1 of 4
Here our aim is to determine the mass flow rate in kg/s and the velocity at the exit of the duct.
