Question
In a 10 cm diameter pipe, pure copper melt flows. The density of copper melt is 7.8 g/cm', and the melt has a dynamic viscosity of 3.12 g/m.s. Calculate the maximum velocity at which the melt flow is laminar.
Transcribed Image Text:In a 10 cm diameter pipe, pure copper melt flows. The density of copper melt is 7.8 g/cm', and the melt has a dynamic viscosity of 3.12 g/m.s. Calculate the maximum velocity at which the melt flow is laminar.
Expert Solution
Step 1 given data

1. diameter= 10cm = 10*10-2m

2. Density = 7.8 g/cm3= 7800 kg/m3

3. dynamic viscosity= 3.12g/ms= 3.12*10-3kg/m.s.

4. Re= laminar , consider 2300

5. V=?

6Vmax=?
