Steps in designing a rocket

[squidie]

110kg sounding rocket that runs on apcp
im trying to understand the steps to building this rocket what equations do i use to find nozzle parameters and estimated burn time etc. initial surface area for the fuel block is 5020cm^2
burn rate is .6 to 1.2mm a second fuel weight is 100kg gamma for exhaust gasses is 1.24 burn temperature is 4300 kelvin and pressure is 9 Mega pascals diameter is 16 cm length is 4 meters i know some physics but have trouble finding the right equations online

You're posting from the US so the first step is to reach out to NAR (nar.org).

I'm still in the design phase but I will eventually do a rocket that needs to be approved

You don't need NAR or equivalent for approval, you need them because that's where you'll find people with the expertise and experience that you're looking for. A 110 kg liquid-fueled rocket is not something that gets designed in isolation.
