A horizontal pipe has a sudden contraction from DN100 to DN80 Schedule 40 steel pipes. The water flows in the smaller pipe at 25 "C with a flowrate of 3020 L/min. The pressure in the larger section is Pi 380 kPa. a) Deternine the type of flow in the smaller and larger pipes. b) Determine the downstream pressure, P2. Calculate the percentage of error that would have occurred if downstream pressure, Pa c) caleulated using Rensoulli's equation. d) State the reason for the pressure difference between Part (b) and Part (c).

Please do not give solution in image format thanku If you want to do your scale model presentation in such a way that BOTH the size AND distance scaled are correct, how far apart would your squishy stress ball Moon and your answer to the previous question need to be? HINT: Multiply the diameter of the scale model Earth that you chose in the previous question by the number of Earth diameters that would fit between the Earth and the Moon. Answer choices: A- You'll need to put one against one wall and hold the other one across the room 240 inches or 20 feet apart B- You will need a volunteer from the audience so you can hold them 72 inches or 9 feet apart C- You could hold them both in front of you at 16 inches or about 1.3 feet apart D- You'll need to tell the kids to use their powers of imagination because the separation would put one of them in the parking lot outside the science center 3600 inches or 300 feet away
