Question

If a pump set with a pipe of 14cm.diameter can drain 2500 metre water per minute. let us write by calculating how much kiloliter water will that pump drain per hour. 1 liter = 1 cubic dcm.
​

Answer 1

14 c m = 14/10 d c m = 1.4 d c m

=2500×10dcm

=25000dcm

= 22 7 × ( 1.4 2 ) 2 × 25000 =227×(1.42)2×25000 cubic.dcm

= 38500 =38500 cubic.dcm = 38500 =38500 litres = 38500 1000 =385001000 kilolitres = 38.5

=38.5 kilolitres ∴

∴ the volume of water 2310 kilometers

Answer 2

Answer:

If a pump set with a pipe of 14 cm diameter can drain 2500 metres water per minute, then calculate how much kilolitres water will that pump drain per hour. [ 1 litre = 1 cubic dcm ] ∴ the volume of water poured by the pipe per hour =38.5×60 kilolitres =2310 kilolitres. Hence the required water =2310 kilolitres.

Step-by-step explanation:

14 cm = 14/10 dcm = 1.4 dcm

<br> 2500 metres

=2500xx10dcm = 25000 dcm

<br> So, the volume of water poured by the pipe per minute <br>

=(22)/(7)xx(1.4/2)^(2)xx25000

cubic.dcm

= 38500

cubic.dcm

= 38500

litres <br>

= (38500)/(1000)

kilolitres

= 38.5

kilolitres <br>

:.

the volume of water poured by the pipe per hour

= 38.5xx60

kilolitres

= 2310

kilolitres. <br> Hence the required water

= 2310

kilolitres
