Water flowing steadily in a horizontal circular pipe with an interior diameter of 20mm. The length of the pipe is 10 m. The pipe is made of stainless steel. The volume flow rate is 0.314 liter/s. Determine the pressure drop through the pipe. The water kinematic viscosity is 1.002×10-6 m2/s. Use the moody diagram to answer.
