THE PROPELLER IN "OPEN" WATER PART

$1-$ A propeller of $3\mathrm{.}0$ m diameter and $0\mathrm{.}8$ pitch ratio absorbs its maximum delivered power when running at $180$ rpm at a speed of advance of $13\mathrm{.}5$ knots $.$ If the propeller torque remains constant, determine the propeller rpm$,$ thrust and delivered power at speeds of advance of $0,2\mathrm{.}5,5\mathrm{.}0,7\mathrm{.}5$ and $10\mathrm{.}0$ knots, using the data of Table $4\mathrm{.}3.$
