What is the laminar flow rate of water in a pipe with an internal radius of r and a length of L m if the pressure difference across the pipe is 2.0 kPa? The water in the pipe has a viscosity of approximately 0.6 mPa-s.    let r =2.5 cm let L=0.5m Describe the effect on the flow rate given each of the following changes. Each change is to the original system and all other variables are held constant.  The radius decreases The pipe length decreases  The fluid viscosity decreases  The pressure difference decreases

Question

3. What is the laminar flow rate of water in a pipe with an internal radius of r and a length of L m if the pressure difference across the pipe is 2.0 kPa? The water in the pipe has a viscosity of approximately 0.6 mPa-s. 

 

let r =2.5 cm

let L=0.5m







  1. Describe the effect on the flow rate given each of the following changes. Each change is to the original system and all other variables are held constant. 

The radius decreases




The pipe length decreases 




The fluid viscosity decreases 




The pressure difference decreases
