water flows in a 1.3 cm diameter pipe that is 30 m long and discharges to the atmosphere. if the pressure at the entrance of the pipe is 0.82kpa gage, determine the mass flow rate and reynolds number of the pipe flow. you can assume the density and viscosity of water to be 998 kg/m^3 and 1.01*10n-s/m^2, respectively. demonstrate clearly whether the flow is laminar or turbulent
