Homework Statement
I know this is more of a physics question, but I tried there and wasn't successful.
I have done a physics experiment measuring the weight as a function time of the discharge of water from a cylindrical bottle with a pinhole at the bottom. What I ultimately want to get at is the weight flow rate as a function of time. I already have the equation describing this scenario, but I don't want to get a theoretical uncertainty, I want an experimental uncertainty for weight flow rate. To get weight flow rate, I took the numerical derivation of the weight using Vernier's LoggerPro software. The constant absolute uncertainty of the weight is ##\pm 0.01## N for all data points. Since I am taking the derivative of the weight values to get weight flow rate, what would be the uncertainty of the weight flow rate. If you need any more data or information, feel free to ask. I have around 2000 data points for 5 trials
Homework Equations
If the uncertainty of the weight is ##\pm 0.01## N, what is the uncertainty of the weight flow rate (derivative of the weight as a function of time)?
The Attempt at a Solution
When I looked this up on the web, almost all of the solutions involved some next level math that I didn't understand. I have been teaching myself calculus (limits, derivatives, integrals) on my own time since I am in Grade 11 (I only take calculus next year) Soooo... I don't know where to start.
