Water flows at the rate of $12\:m^3/s$ in a $6\:m$ wide rectangular channel. A hydraulic jump is formed in the channel at a point where the upstream depth is $30\:cm$ (just before the jump). Considering acceleration due to gravity as $9.81\:m/s^2$ and density of water as $1000\:kg/m^3$, the energy loss in the jump is 

  1. $114.2\:kW$
  2. $114.2\:MW$
  3. $141.2\:h.p.$
  4. $141.2\:J/s$
