A $41-$mm diameter Schedule $40$ galvanized steel pipe is connected to a water main as shown in the figure below. The pressure in the water main is $350$ kPa $,$ the flow in the pipeline is regulated by a globe valve, and flow exits the pipeline through a nozzle with an exit diameter of $30$ mm $.$ A globe valve is to be selected such that a water fountain as high as $5$ m can be generated. The $90$ bend between the globe valve and the pipe exit is estimated to have a loss coefficient equal to $1\mathrm{.}2,$ the nozzle is estimated to have a loss coefficient of $0\mathrm{.}05,$ and the galvanized steel pipe is estimated to have an equivalent sand roughness of $0\mathrm{.}1$ mm $.$ Estimate the maximum allowable loss coefficient for the open globe valve. Assume the water temperature is $20C.$
