Equation of Continuity--Three Fire Hoses and Pipes
Three fire hoses are connected to a fire hydrant. Each has a radius of 0.020 m. Water enters the hydrant through an underground pipe of radius 0.080 m. In the pipe the water has a speed of 3.0 m/s. How many kilograms of water are poured onto the fire in one hour? What's the water speed in each hose?
A1 x V1 = A2 x V2
m = V x rho
I'm not really sure what other equations are relevant.
I don't even know where to start. I need the volume...I think, and I'm very confused.
