Water at `20^(@)` is flowing in a pipe of radius `20.0 cm` . The viscosity of water at `20^(@)C` is `1.005` centipise. If the water's speed in the centre of the pipe is `3.00m//s`, what is water's speed:
(a) `10.0cm` from the centre of the pipe(half way between the centre and the walls)
(b) at the wall of the pipe?

Water flows at a speed 5 cm s^(-1) through a pipe of radius 2 cm. The visosity of water is 0.001 PI. The Reynolds number and the nature of flow are respectively

Water is flowing in a pipe of diameter 4 cm with a velocity 3 m//s . The water then enters into a tube of diameter 2 cm . The velocity of water in the other pipe is

Water flows through a pipe of diameter 8.0 cm with a speed of 10.0 m/s . It then enters a smaller pipe of diameter 3.0 cm . What is the speed of the water as it flows through the smaller pipe ?

Water at 20^(@)C is flowing in a horizontal pipe that is 20.0m long.The flow is laminar and the water completely fills the pipe. A pump maintains a gauge pressure of 1400Pa , at a large tank at one end of the pipe. The other end of the pipe is open to the air, The viscosity of water at 20^(@)C is 1.005 poise (a) If the pipe has diameter 8.0 cm , what is the volume flow rate? (b) What gauge pressure must the pump provide to achieve the same volume flow rate for a pipe with a diameter of 4.0cm ? (c) For pipe in part (a) and the same gauge pressure maintained by the pump, what does the volume flow rate become if the water is at a temperature of 60^(@)C (the viscosity of water at 60^(@)C is 0.469 poise?

Water is flowign through a cylindrical pipe of cross section area 0.09 pi m^(2) at a speed of 1.0 m/s. If the diameter of the pipe is halved, then find the speed of flow of water through it

From a pipe of inner radius 0.75 cm, water flows at the rate of 7 m per second. Find the volume in litres of water delivered by the pipe in 1 hour.

Water is flowing in a horizontal pipe of non-uniform area of corss section. The velocity of water at a place, where the radius of pipe is 0.01 m is 25 m/s. What will be the velocity of water where the radius of pipe is 0.02 m?

Models of torpedoes are sometimes tested in a horizontal pipe of flowing water, much as a wind tunnel is used to test model airplanes. Consider a circular pipe of internal diameter 25.0 cm and a torpedo model aligned along the long axis of the pipe. The model has a 6,00 cm diameter and is to be tested with water flowing past it at 2.00 m/s. (a) With what speed must the water flow in the part of the pipe that is unconstricted by the model? (b) What will the pressure difference be between the constricted and unconstricted parts of the pipe?
