1. A four stroke, 12 cylinder medium speed Diesel engine i used to power a single screw ship. The engine has a brake mean effective pressure of.1.* MP2 cylinder bore 04 mm and stroke length 0.40 m Engine and propeller are the contribution of ratio 31. The hull surface area (S^ - 2200 m^ prime ,C=0.0032. ed with a gearbox of reduction appendages (0) = 0.20, t = 0.03 She is equipped with a propeller having D = 2.8r . It is intended that the propeller aperates with J=||.||| , wame the open water efficiency 10.70 Find sqrt(inn) =
Engine revolution
b. Ship spoed
Power demand from the engine
If the ship tows an identical sister ship, what ahall be the power and speed be
(Assume that relative rotative efficiency and transmission efficicacies are equal to
eta ab = eta m -10)
can u help me for this one please
