Question

A River of salty water is flowing with a velocity 2 m/sec. If the density of the water is 12 m/s then the kinetic energy of each of cubic metre of water is​

Answer 1

Answer:

Explanation:

As this is a case of mass flow system. The kinetic energy of the system will be as

(1/2)d×V×v²,where d is density, V the volume and v the velocity at any point. As per question d=1.2 gm/cc=1200 kg/m³,V=1m³,v(velocity)=2m/s.Thenk.e.={(1/2)1200×1×2²}=2400J.Ans..

Answer 2

Answer:

the kinetic energy of each of cubic metre if water is 2.4 KJ or 2400J.
