The known angular velocity of link AB is wAB and the unknown angular velocity of link BC is wBc. Determine the velocity vectors V B, V C, and WBC using a relative motion analysis. Reduce/simplify all expressions as far as possible. The only parameters that should appear in your symbolic solution include wAB, LAB, LBC, 0, and o. Finally, numerically evaluate the three velocity vectors using values LAB 2 m, LBC = 1.5 m, wAB = 0.25 rad/s, 0 = 30°, and o = 10°.

Consider steady flow of air through the diffuser portion of a wind tunnel. Along the centerline of the diffuser, the air speed decreases from uentrance to uexit as sketched. Measurements reveal that the centerline air speed decreases parabolically through the diffuser. Write an equation for centerline speed u(x), based on the parameters given here, from x = 0 to x = L.
Water at 20◦C flows along the streamlines shown in Figure3.11. The (gauge) pressure, velocity, and elevation at Point1 are 15.0 kPa, 1.0 m/s, and 5.02 m, respectively, and thevelocity and elevation at Point 2 are 0.5 m/s and 5.21 m,respectively. Estimate the pressure at Point 2. The given answer was P2 = 13.5 kPa. Show detailed solution pls thank you.
A certain lake is proposed as a landing area for large jet aircraft. The touchdown speed of 100 mph upon contact with the water is to be reduced to 20 mph in a distance of 1500 ft. If the deceleration is proportional to the square of the velocity of the aircraft throug the water, a=-kv^2 , find the value of the design parameter k . This parameter serves as a measure of the size and shape of the landing gears vanes that plow through the water. Also, determine the time elapsed during the spedified interval. (1 mile=5280 ft)

Some students want to visualize flow over a spinning baseball. Their fluids laboratory has a nice water tunnel into which they can inject multicolored dye streaklines, so they decide to test a spinning baseball in the water tunnel. Similarity requires that they match both the Rey n olds number and the Strouhal number between their model test and the actual baseball that moves through the air at 90 mi/h and spins at 300 rpm. Both the air and the water are at 68°F. At what speed should they run the water in the water tunnel, and at what rpm should they spin their baseball?
A 45 grams (0.045 kg) golf ball of diameter equal to 43 mm fell into a 2m deep lake. Neglect inertia at the moment of impact. Assume viscosity of 1.12x10-3 Ns/m2 , water density of 1,000 kg/m3 and Cd=0.5. Sphere volume equals 4π r³ /3. 1. How long will it take from the moment it hits the surface until it gets to the bottom? 2. If one estimates the Cd with Cd=24/Re formula, the settling velocity would be unrealistically large. Why?
How would I calculate the fluid acceleration along the nozzle centerline.
