- Homework Statement
- Pipework between a buffer tank and filter is 100 mm diameter. Flow rate of beer is 400 hl h-1. Density of beer is 1010 kg m-3 and viscosity is 0.0025 Pa s. Calculare Reynolds no. For the flow through the pipework
- Relevant Equations
- Re = (density x mean velocity x diameter)/ viscosity
First calculate mean velocity:
400 hl h-1 = 40,000 L / h-1 = 666.67 L/min
1L/min = 10^ -3 m3/min
666.67 L/min = 0.666 m3/min
= 0.0111 m3/sec
Cross sec area = (3.14)(0.1/2)^2 = 7.853 x 10^-3 m2
0.0111/7.853 x 10^-3 = 1.413 m/s
Re = (1010)(1.413)(0.05)/0.0025
= 28,542.6
Am i right here?
Re above 4000 is turbulent which i thought was more for CIPs rather than beer transfers
