Assuming that the pressure is uniform on each of the channel walls, determine the pressure difference between the upper and lower wall that is needed if the required net force on the two walls is 1850 N pointing downward (in the negative y-direction). Use a sign convention that a positive pressure difference or gradient means the pressure at the higher y-position is higher. The value of the pressure difference is Pa. The value of the pressure gradient across the channel is Pa/m. b) Your team agree that, from experience, the average velocity of the fluid is

Question
a) Assuming that the pressure is uniform on each of the channel walls, determine the pressure difference between the upper and lower wall that is needed if the required net force on the two walls is 1850 N pointing downward (in the negative y-direction). Use a sign convention that a positive pressure difference or gradient means the pressure at the higher y-position is higher. The value of the pressure difference is Pa. The value of the pressure gradient across the channel is Pa/m. b) Your team agree that, from experience, the average velocity of the fluid is v = 49. Assuming that the velocity is uniform across the channel, and neglecting gravitational effects, determine the curvature R required to generate this force with this flow velocity. Use a sign convention that a positive value indicates that the centre of the radius is above the channel, i.e. the middle of the channel is bent downwards. A negative radius indicates the middle of the channel is bent upwards. The curvature radius R is m.

Water flows in a channel with uniform curvature R. The channel has heighth- 4 mm and width w=215 mm (normal to the drawing plane) as shown in Fig Q3. The curved part of the channel has a length of 2 =100 mm in the x-direction. You can assume that the channel height is very small compared to the curvature radius. Neglect effects of gravity. channel YA 1 lower wall h upper wall centreline
