Hello! Background I have a hobby in creating an automated home, controlling lights, reading temperatures, and so on from self build sensors and actuators. For a while I have had force sensing resistors under each leg of my bed so I can messaure my own weight every day, sleeping patterns and so on. This has been working quite good for a while, but the sensors does not stand the constant pressure and fails. I need a new solution. Setup Instead of a sensor under each leg, the bed will fully stand on a plastic tube filled with water. The tube will have a liquid pressure sensor in one end and a stop in the other end. Problem I need to know the pressure on the sensor so I can buy a suitable sensor for that working range. Data The tube will have a diameter of about 10mm. The length of the tube will be around 10m to go around and under all legs of the bed. The pressure in total will be around (60+70+30) = 1600N. The bed stands only on the tube and the tube will be filled with water. Question In Bar, what will be the pressure applied on the sensor?
