Awater distribution system is composed of three sections, by which the water flows at 10 1.325 kpa and 25%. in section i , the water flows through a mass flow rate of m1 20.0 kg/s. in section 2 the flow occurs in a cross-sectional area of 0.003m2. while in section 3 the fluid in question flows with a volumetric flow rate q3 0.06 m3 s. it is known that sections 1 and 2 are inlet nozzles discharging in section 3. it is also known that the entire process is carried out in a steady state. considering the above, determine the mass flow rate, in kg/s, and the flovw velocity, in m/s at the entrance of section 2, considering the fluid density 997 kg/m3
