The drag of a football is investigated in a water tunnel with a quarter-scale model and matching the full-scale Reynolds number. If the actual expected speed is assumed at 95 km/h, estimate the ratio of the drag force between the model and the full-size football. Use the fluid properties (for air and water) as listed in Table 1.1 and assume that the force F on the ball varies as F ∼ ρU2D2, where D is the ball diameter.
the 30 mg aircraft is climbing at the angle theta15 with a thrust t of 180 kn. at the instant shown its speed is 300
a frictionless piston-cylinder device fitted with stops above the piston contains 1.2 kg of air at 200degc and 700 kpa.
if p150kn determine the elastic elongation of rod bc and the decrease in its diameter. rod bc is made of a-36 steel and
A 3L, 4-stroke, V6 engine with a 9.5:1 compression ratio delivers 205 N-m at 3600 RPM. At this speed, air enters the cylinder at 85 kPa and 60 C and combustion ends at 20 crank angle after top-dead-center. It is known that the engine is square and th..
water enters a smooth-thin-walled tube of 1 inch in internal diameter at 50f and leaves at 150f. heat is supplied to
A 40 kg container is initially at rest and then is pushed by a hydraulic cylinder with a force (kN) = 160 - 10 s. The coefficient of friction between the container and the floor is .26. Give one reason why it may be quickest to use energy methods to ..
air is contained in a vertical cylinder fitted with a frictionless piston and a set of stops as shown in the sketch
An evacuated 1-ft3 tank is connected by a valve to a nitrogen supply line flowing air at 120 psi and70oF. A valve is opened allowing air to flow into the tank until the pressure reaches 90 psi. How much mass flowed into the tank and what is its final..
