Question

The area of a cross section of a pipe is 5.4cm^2 and the water is pumped out of it at the rate of 27km/hr.Find in litres the volume of water which flows out of the pipe in one minute.

Answer 1

The area of cross section of a pipe is 5.4 centimetres square and the water pump out of it at the rate of 27 kilometre per hour find the volume of water which flows out of the pipe in 1 minute

Math - Reiny Tuesday, January 10, 2017 at 6:29amrate = 27 km/hr 
= 2700000 cm / 60 minutes 
= 45000 cm/min 
so in 1 minute, the water flows 45000 cm 

volume = area of base x height 
= 5.4 cm^2 x 45000 cm 
= 243000 cm^3Math - sarthak srivastava Saturday, November 11, 2017 at 9:31am243Math - Mudit Thursday, February 22, 2018 at 2:56amAs rate= 27km/h 
So when we change it into cm it becomes =2700000cm/60mins 
= 45000cm/min 
So in 1minute 45000cm water is pumped 
As the area of base is 5.4cm^2 
So volume=area of base × height 
5.4×45000 
=243000cm^3 
Hence,the volume of water pumped in one minute is 243000cm^3.Math - Anonymous yesterday at 11:38pm243 litres

Answer 2

s=27 km/hr
  =27x 5/18  60 m/min
  450m/min
volume=450000 x 5.4 =2430000cm³
          =2430 lts
