Textbook Question
Chapter 10, Problem 44P
We have used an experimental setup similar to Example 10.1 to determine the value of a spring constant. The deflection caused by the corresponding weights are given in the accompanying table. What is the value of the spring constant?
| Weight (lb) | The Deflection of the Spring (in.) |
| 5.0 | 0.48 |
| 10.0 | 1.00 |
| 15.0 | 1.90 |
| 20.0 | 2.95 |

Q2/
In a design of a portable sprinkler system, the following information is given:
•
•
The sprinklers are distributed in a square pattern with radius of the wetted circle of
the sprinkler=15 m
Consumption rate = 10 mm/day
Efficiency of irrigation = 60%
Net depth of irrigation (NDI)= 80 mm.
Find the following:
1-Sprinkler application rate if HRS = 11.
2-Number of pipes required for irrigation.
(50 Marks)
3-Discharge of sprinkler, diameter of nozzle, and the working head pressure if C=0.90.
4-Diameter of the sprinkler pipe for Slope=0.
5-Pressure head at the inlet and at the dead end of the sprinkler pipe for Slope=0.
