A maximum flow rate of 6 CFS is available for a river model
A maximum flow rate of 6 CFS is available for a river model. This corresponds to 30,000 CFS for the prototype. 
 
 What is the scale of the model in terms of the prototype size?

 What is the scale of the model in terms of the prototype size?
Solution
Given - Q of model = 6cfs
Q of prototype=30000
The scale of model=(Q of model /Q of prototype)
=6/30000
=1/5000
Hence Scale of model= 1/5000 ANSWER
