The Fanning equation and the Darcy-Weisbach equation both relate the pressure drop with the dynamic pressure of the flowing fluid in a channel. What is the physical significance of the pressure drop? Why is it needed to be determined?
A vertical channel of diameter 5 cm and length 10 m is conducting water in upward manner( water viscosity= 1x10 -6 m2/s , water density =1000 kg/m3 ). For the presence of laminar flow regime determine the maximum amount of flow rate approximately ( Use pi number as 3,14 )ANSWER: 0,09 kg/s
Water flowing through a pipe of constant cross section, 11 cm in diameter, as shown in Fig. shown in the figure below. It has a speed of 5 m/s at the bottom and has traveled 2 m in height before being dumped into the environment, where the local atmospheric pressure is 1 atm.
Assuming conservation of flow, what is the velocity of the water as it leaves the pipe
(b) Calculate the pressure using Bernoulli's equation.
(C) Determine the time, in seconds, required for 1 m³ of water to flow through the opening of the pipe.
