Question: A free liquid jet, as in Fig P3.152, has constant ambient pressure and small losses; hence from Bernoullis equation z + V2/ (2g) is constant

A free liquid jet, as in Fig P3.152, has constant ambient pressure and small losses; hence from Bernoulli’s equation z + V2/ (2g) is constant along the jet. For the fire nozzle in the figure, what are (a) the minimum and (b) the maximum values of θ for which the water jet will clear the corner of the building? For which case will the jet velocity be higher when it strikes the roof of the building?
