What is the CGPA required for B,Tech degree
A ship has a length of 150 m and wetted area of 3000 m2. A model of this ship 5m in length when towed in fresh Water at 2m/s produces a resistance of 39.24N. The ship surface has skin resistance of 49.05 N/m2 at a velocity of 3 m/s and the velocity index is 1.85. The corresponding values for the model surface towed in fresh water are respectively 16.38 N/m2, 3m/s and 1.90. Calculate :
(i) the corresponding speed of ship
(ii) the shaft power required to propel the ship at this speed through sea water (p =1030 kg/m3). Take the propeller efficiency as 75%.
