3. A ship travels in seawater at a speed of 15 knots and expends 7000 hp. The ship's hull is 150 m long and has a surface area of 5000 m2. Assume that all of the ship's drag is due to skin friction and that the ship's hull can be treated as a flat plate with equivalent length and surface area. A)...

Problem: For completely rough flat plates (i.e., plate surfaces on which urk,/v> 70), Schlichting developed conrelations for skin-friction, ef, and (one-sided) drag. Co. coefficients, viz. -2.5 -2.5 c 2.87+1.58 log1o and Cp1.891.62 log1o 10g10 k where a is distance along the plate, L is plate length and k, is surface-roughness height. For the rudder of a motorboat, compute cyat the trailing edge and C using the smooth-surface formulas, given below, and the Schlichting formulas. The boat is moving at 16...

2. (25 pts) Engine oil flows with a velocity of 6 m/s over a flat plate having 1m length and 1 m width. The oil has a free stream temperature To= 80 °C and the plate surface temperature is maintained at Ts = 0 °C. a. Determine whether the flow over the plate transitions to turbulent regime. b. Calculate the average friction factor and the average heat transfer coefficient for the plate by using the appropriate correlations. c. Calculate the...

Problem 3: A thin flat plate of length L-120 mm, thickness t=4 mm, width W=30 mm, and thermal conductivity k=20 W/m-K is thermally joined to heat sinks at different temperatures, where T(x = 0) = To-100 C and T(x = L) = T,-35°C. The top surface of the plate is subjected to uniform heat flux q"-20 kW/m2, and the bottom surface of the plate is subjected to uniform convection with a convection...

Qi. A flat plate of width 1 m and length 0.2m is maintained at a temperature of 32°C. Ambient fluid at 22"C fBlows across the top of the plate in parallel flow. Determine the average heat transfer coefficient, the convection heat transfer rate from the top of the plate, and the drag force on the plate for the following: (a) The Buid is water flowing at a velocity of 0.5 m/s. o) Water is flowing at a velocity of 2.5...
