Problem Description :
Three containers are kept on a horizontal surface. The dimensions of all the containers is given in Fig.1 . The base of each container is kept on a pressure sensor (PS). Each container is placed below a tap. All containers are symmetrical about the central axis. The whole setup is shown in Fig. 2
- Pressure Sensor/ Pressure Transducer:
For this problem, we have chosen this sensor to measure the pressure at the base
- Working:
More the pressure, more the value sent as output
Note : In reality, this is known as a force sensor
The pressure sensor is further, a part of the electric circuit shown. The circuit involves :
- Microcontroller – Arduino
- Pressure Sensor
- LED
- LDR
- Multimeter as Ammeter
Hint : LDR stands for ‘Light’ Dependent Resistor
Note : Each container has a separate circuit (Fig.3) for itself attached
Arduino IDE code:
Hint : Understand the problem statement, the setup of the problem, the circuit and the code thoroughly. Note that, you just need to get the gist of what the code is trying to do!
- Based on your understanding,
Answer the Question Parts shown below
Question Parts :
Part- (a)
The taps above respective containers are turned on and water is allowed to flow into the containers. The experimenter keeps a track of the height of the water column ‘h’ which gets accumulated in the containers w.r.t time and plots the graphs for the same as an observation. (Taps are not identical)*
Graphs are as follows :
- Is there any time instant where the readings of the current values are same on atleast 2 ammeters? And if you find any, then find the volume of water filled in the 3 containers at that time instant.
Part-(b)
Part-(c)
- Draw the simplified schematic circuit diagram and a flowchart which simplifies Fig.3
(Optional)
Conclusion :
Understand & draw the circuit. Try to understand the motive behind the code. Basically, there is a type of procedure/flow to approach this problem. Try to grab that flow.
