The pressure required at a pump outlet to create a flowrate of $0\mathrm{.}6m^3{s}^{-1}$ of water $($density of $1000k\frac{g}{m^3})$ is found to be

$259$kPa. What is the frictional loss $($J$)$ per kg of fluid $($do not enter units in the answer box$)$ from point $1$ to $2?($We are

looking for a loss, so negative energy is implied and the answer will be a positive quantity$)$
