**Week 4 Review Assignment **

*I pledge to support the Honor System of ECPI. I will refrain from any form of academic dishonesty or deception, such as cheating or plagiarism. I am aware that as a member of the academic community, it is my responsibility to turn in all suspected violators of the honor code. *

*I understand that any failure on my part to support the Honor System will be turned over to a Judicial Review Board for determination. I will report to the Judicial Review Board hearing if summoned.*

NOTE: Handwritten work is not acceptable. All work must be typed and submitted on a Word Document.

* Identify and list* all variables from the problem.

*W*rite the equation(s) you will use that are *found in the textbook*. Do not use any other equations.

*S*ubstitute your variables into the equation. YOU MUST INCLUDE UNITS IN ALL PLACES OF YOUR EQUATIONS.

**You must show all of your work, even “simple” calculations*** .* During your calculations, please use 3 decimal places or 3 significant decimal places. This does not apply to financial cost calculations.

Clearly identify your answer * with correct units*.

CORRECT METHOD:

**INCORRECT METHOD:** **p2 = (W * a)/g + p1 = a^2 – Ap – μ = 0**

Problem1

Compute the hydraulic radius for the section shown in the figure below if water flows at a depth of 2.0 inches. The section is that of a rain gutter for a house.

Problem 2

Compute the hydraulic radius for a circular drain pipe running half full if its inside diameter is 300 mm.

Problem 3

Calculate the force required to hold a flat plate in equilibrium perpendicular to the flow of water at 25 m/s issuing from a 0.075m diameter nozzle.

Problem 4

Calculate the force that must be exerted on the pipe shown to hold it in equilibrium. The elbow is in a horizontal plane and is connected to two 4-in Schedule 40 pipes carrying 3500 L/min of water at 15°C. The inlet pressure is 500 kPa. Energy losses are negligible. (Hint. This problem is similar to Example Problem 16.3 found in the textbook on page 423)
