Step 1
1 mile = 5280 feet 47 miles/hour = 47 * 5280 feet/hour = 248160 feet/hour 1 hour = 3600 seconds 248160 feet/hour = 248160 / 3600 feet/second = 69 feet/second Show more…

The foils of a surface-piercing hydrofoil watercraft have a total effective area of $7.5 \mathrm{ft}^{2} .$ Their coefficients of lift and drag are 1.5 and $0.63,$ respectively. The total weight of the craft in running trim is 4000 lb. Determine the minimum speed at which the craft is supported by the hydrofoils. At this speed, find the power required to overcome water resistance. If the craft is fitted with a 150 -hp engine, estimate its top speed.
A transport truck driving at a constant speed of 82.0 km/hr on a flat stretch of highway must produce 2,634 N of force to overcome rolling friction and air resistance. How much horsepower is required from the engine under these conditions ? Ignore any mechanical losses in the drivetrain. {1 hp = 746 W}

An automobile has a characteristic length and area of 8 ft and 60 ft2, respectively. When tested in sea-level standard air, it has measured velocities of 20, 40, and 60 mi/h and drag forces of 31, 115, and 249 lbf, respectively. The same car travels in Colorado at 115 mi/h at an altitude of 3500 m. Using dimensional analysis, estimate its drag force (in lbf). Using dimensional analysis, estimate the horsepower required to overcome air drag (in hp)
