There is a pipe whose diameter narrows smoothly from 10cm to 5.0cm. The pressure at where this pipe's diameter is 5cm is 50kPa. Given water's density of 1000kg/m^3, and a flow rate of 5.0L/s, what is the pressure at the point where the pipe's diameter is 10cm? First the continuity equation: Q=Av 0.005L/s=[pi(0.05/2)^2]v v=2.546m/s Then, Bernoulli's equation: Substitute v1 for A2v2/A1 P1=50000+(.5)(1000)(2.564^2-[(pi*.05^2)(2.564)/(pi*.1^2)]) I left the potential energy out of the equation because it is negligible givien the number of significant figures we have. Even though I did the calculation with adding potential energy it is still wrong. So I got 79993Pa. I know it is very wrong but I cannot check it since I don't have the answers. Any help please?
