Question

A liquid of specific gravity 0.8 is flowing in a
pipe line with a speed of 2 m/s. The K.E. per
cubic meter of it is
1) 160 J X 1600 J 3) 160,5 J 4) 1.6 1.​

Answer 1

Answer:

option 2 is correct

Explanation:

density = 0.8*1000 = 800 kg/m^3

KE = 1/2 * 800*2^2= 1600 J/m^3

Answer 2

Answer:

option 2 is correct

Explanation:

density = 0.8*1000 = 800 kg/m^3

KE = 1/2 * 800*2^2= 1600 J/m^3
