Question

Please solve this.................

Answer 1

Flow rate = Volumetric flow rate/Area

 

Area = pi * r2 = (22/7)*7/2*7/2= 38.5 cm2  

Volumetric flow rate = 192.5 l/min.

Since 1l = 1dm3 = 1000 cm3

So, Volumetric flow rate = 192.5 *1000 cm3/min

 

So, flow rate = 192.5 *1000 cm3/min / 38.5 cm2  

flow rate = = 5000 cm/min = 5000*0.00001 km/(1/60 h) = 3 km/h
