Water is flowing in a horizontal pipe (1 inch, schedule 40) with a velocity of 2 ft/s and a pressure of 10 psia. The water enters a second section of pipe that is 4 inch schedule 40. What is the pressure in the section of pipe if friction can be ignored?
Note: The inner diameter of 1 inch pipe = 1.049 inches
The inside diameter of the 4 inch pipe =4.026 inches
