A three-passenger submarine has to be operated underwater for a survey of marine life. Different choices of power plants are available, ranging from 20kW to 35kW in steps of 5kW. The submarine's shape can be approximated as a cylinder. Your services have been acquired with a good salary being a fresh engineer with expertise in fluid mechanics. The cylindrical dimensions must be chosen considering the drag forces on the submerged body of the submarine. The following requirements have been provided to you: a. Submarine operator = 1 b. Submarine passenger = 3 c. Space for media equipment = Up to 0.5m d. Oxygen operating equipment = ? e. Duration to stay underwater = 5 hours f. Empty space required for different purposes = 2m g. Power plant space = 2.5m h. The total area should not increase by more than 25m. 1. The maximum speed range for the submarine = 8 to 12 knots. j. Ocean Temperature varies from 0 to 6C. k. 5 to 10% safety is to be included in all the calculations. 1. The submarine has to be operated in the area of the ocean under the control of Pakistan. You are required to suggest appropriate dimensions of the cylindrical shape of the submarines and choice of power plant required to achieve the maximum speed within the given range. Determine the drag against the required power plant. Outline the reasons for choosing the suitable power plant for the submarine. Justify your calculations with the standard graphs/values available in books/internet with authority. Guidelines: Page 2/4 Apply the knowledge of fluid mechanics you gained during your engineering on the topics of laminar flow, turbulent flow, boundary layers, boundary layer separation, drag, and shear stress etc.. -23 R A three-passenger submarine has to be operated underwater for a survey of marine life.
