## Homework Statement

A fluid of density 867 kg/m3 flows through a circular duct of diameter 40.60 mm with a mass flow rate of 14.63 kg/s. The fluid velocity in m/s is?

## Homework Equations

mass flow rate [kg/s] = density [kg/m3] x velocity [m/s] x area [m]

## The Attempt at a Solution

14.63 = 867 x velocity [m/s] x pi(40.60/2000)^2

therefore: velocity = 13.03 m/s

Though from my notes:

Correct Answer: 1.190 m/s

Am I doing something wrong or is the answer from my notes just wrong?

Thanks in advance!
