A pipe transports water in a 4-cm-diameter pipe with an average velocity of 10 m/s. The pipe undergoes a 90 degree bend and exits out a 2-cm-diameter nozzle. Assuming no friction losses in the bend, the total force of teh water on the bend is nearest:
A) 1070 N
B) 1180 N
C) 729 N
D) 502 N
A drag force meter is used to estimate the wind velocity during a hurricane. A force of 4.8 N is measured by the meter and the meter has a cross sectional area of 16.9 cm2 with a coefficient of drag of 0.66. What is the wind velocity in mph? Let the ..
