🚢 Sternwheel Steamboat: Paddle Thrust, Slip and Hull Drag (2D)

Side view of a river steamboat driven by a stern paddle wheel. Set wheel radius, rpm, blade immersion, blade width, hull drag and river current, and see the speed at which blade thrust balances hull resistance, the slip, the shaft power and the coal burned. The balance is checked against a time integration and a closed-form law, with four in-page numerical checks.
