🛸 Inspection ROV: Thruster Thrust, Hull Drag, Terminal Speed, Station Keeping in a Current and Battery Endurance (2D side view)

Side view of a small inspection ROV in a water current. Set thruster rpm and propeller size, number of thrusters, hull drag area, mass, current, depth, water density and battery, and see thrust against drag, terminal speed, the rpm needed to hold station, depth pressure, power and endurance. Thruster rpm range follows the 3D page, with five in-page numerical checks; illustrative coefficients.
