University of Missouri-Columbia Department of Mechanical & Aerospace Engineering MAE 3400 - Fluid Mechanics (Fall 2023) Problem Set 11 Y A0 00 (=Y oL 4 T 10 0 V= D Y {01 [=] 0} 4l | D PR Due: 5pm on Friday, November 10, 2023! Please submit original hardcopy of your problems with following guidelines: Please scan your homework before submitting your original copy in case your graded set is missing! Please print this page and the following page out and staple them on the top of your work. Please submit your set in the box placed in hall just outside Room E3409. Please write legibly. If the grader can’t read it, they can’t grade it. Start each problem on a new sheet of paper. Number each page. Include a diagram for each problem as appropriate. Define all variables next to diagram. Recommended to solve the problem with variables and insert values only at the very end - this helps the grader give you partial credit and helps you check your work. Box in your final answer.

Mizzou Engineering Problem Set 11 MAE-3400 FS2023 All problems are drawn from A. Gerhart et. Al, 9-th Ed. i N\ Take kinetic energy correction factor @ = 1 for all problems in this set. - A ' e B i 12 ft Problem 1 (20 points) Concepts: Energy equation 4t A water siphon having a constant inside diameter of 3 in. is arranged as shown. If | . the friction loss between A and B is 0.8V /2, where V is the velocity of flow in the 3in—R— siphon, determine the flowrate involved. i’* o Problem 2 (20 points) Concepts: Energy equation 6 in. f— For the 180° elbow and nozzle flow shown, determine the loss in | i available energy from sections (1) to (2). How much additional available el i energy is lost from section (2) to where the water comes to rest? 12‘Lin- . p1 = 15 psi : JJ V1 =5 ftis "’%) ~ f Section (1) Problem 3 (20 points) Concepts: Energy equation Section (2) Water is to be moved from one large reservoir to another at a higher —— elevation as indicated. The loss of available energy associated with diameter pipe 2 2.5 ft3/s being pumped from sections (1) to (2) is loss = % ft?/s?, where I/ is the average velocity of water in the 8-in.-inside-diameter piping involved. Determine the amount of shaft power required. Section (1) Problem 4 (20 points) Concepts: Energy equation p=749.5mm Hg__;L Elevation = 10 m e ; Water at 10 °C flows through the system shown at 0.2 m3/s. Energy loss D=30cm in the 40-cm pipe is negligible. Energy loss in the 30-cm pipe is known to be 1.5V2. A mercury manometer indicates that the absolute pressure Elaatitn at the top of the 30-cm pipe is 749.5 mm Hg absolute. The pressure of Water 40-§n$dr?ameter the surroundings is 101,330 Pa.
