Consider incompressible flow in a circular channel. Derive general expressions for Reynolds number in terms of (a) volume flow rate Q and tube diameter D and (b) mass flow rate mp and tube diameter. The Reynolds number is 1800 in a section where the tube diameter is 6 mm. (c) Find the Reynolds number for the same flow rate in a section where the tube diameter is 6 mm.

a) , b) , c) 1600

Explanation:

a) The Reynolds Number is modelled after the following formula:

Where:

- Fluid density.

- Dynamics viscosity.

- Diameter of the tube.

- Fluid speed.

The formula can be expanded as follows:

b) The Reynolds Number has this alternative form:

c) Since the diameter is the same than original tube, the Reynolds number is 1600.

explanation:

assault rifle is a rapid-fire, magazine-fed rifle designed for military use. it is a shoulder-fired weapon that allows the shooter to select between semi-automatic (requiring you pull the trigger for each shot), fully automatic (hold the trigger and the gun continuously fires) or three-shot-burst modes.
