ENS5170 : Engineering Systems - Water Level in Draining Tanks - Engineering Assignment Help

Assignment Task :

1. Summary 

This laboratory introduces the basic principles involved in Fluid Mechanics including the Bernoulli's  equation and its application. The apparatus consists of a tank which can be drained using a valve  installed near its bottom. The laboratory is designed to provide the students with insights into the  influence of the parameters involved in the governing equations of the system. Various experiments  will be run during the laboratory period. The students will be expected to calculate data based on the  theory presented herein and compare that data with the experimental results. 

2. Objectives 

1. Determine the changing effect of parameters on the solutions of differential equations.

2. Determine the behaviour of the draining tanks over time. 

3. Develop the models for representing the real world system, and comparing the performance  of the model with the real world data. 

3. Theory 

Bernoulli's equation relates the pressure, velocity, and height of any two points (1 and 2 in Fig. 1) in  a steady streamline flowing fluid of density (?). Bernoulli's equation is usually written as follows: 

1. Experimental Procedure  

1. Measure the dimensions of the container (tank) including the top diameter, bottom  diameter, and the diameter of the outlet valve (The height of the tank is 35cm).

2. Fill the tank with water. 

3. Measure water level using the ruler. This will be water level at t=0. 

4. Open the valve and start the stopwatch at the same time. 

5. Close the valve and stop the stopwatch when 10s passes.  

6. Write down the new level of water. 

7. Repeat this process 10 times.
