A horizontal pipe 17.00 cm in diameter has a smooth reduction to a pipe 8.50 cm in diameter. If the pressure of the water in the larger pipe is 8.00 104 Pa and the pressure in the smaller pipe is 6.00 104 Pa, at what rate does water flow through the pipes? The velocity is the same for both, how do i convert the answer to kg/s

Flow is given by the product of the water velocity (m/s) and cross sectional area (m²), multiplied by the density ρ (1000 kg/m³).

or,

Q=A1*V1*ρ (in kg/s)

for the answers, which velocity do i chose to convert to kg/s
