A horizontal segment of pipe tapers from a cross sectional area of 50 cm2 to 0.5 cm2. The pressure at the larger end of the pipe is 1.26 105 Pa and the speed is 0.029 m/s. What is the pressure at the narrow end of the segment? Pa

Please help!

Due to the flow contraction, the velocity at the exit (Vout) will be 100 times the velocity at the entrance (Vin). That results from the incompresible-flow continuity equation.

The pressure at the entrance, combined with the Bernoulli Equation, Vin and Vout, will tell you the pressure at the exit.

You should use a ^ before exponents, when typing equations and scientific-notation numbers. I am sure you mean 10^5 and not 105.

Can someone or drwls please give a more detailed explaination please. I don't understand it still i keep getting it wrong.
