1. Water at 20-C flows in a 10-cm-diameter smooth horizontal pipe at the rate of 0.004 m3=s. Estimate the maximum velocity in the pipe and the head loss over 40 m of length. Use the power-law velocity distribution.
2. SAE-30 oil at 20-C is transported in a smooth 40-cm-diameter pipe with an average velocity of 10 m=s. Using the power-law velocity profile, estimate
(a) the friction factor,
(b) the pressure drop over 100 m of pipe,
(c) the maximum velocity, and
(d) the viscous wall layer thickness.
A 55.0 kg circus performer oscillates up and down at the end of a long elastic rope at a rate of once every 8s. The elastic rope obeys Hooke's Law. By how much is rope extended beyond its unloaded length while the performer hangs at rest?
The speed of sound at 0oC is 331 m/s. At another temperature, the speed of sound is measured to be 343 m/s. Evaluate what is this temperature
On a banked race track, the smallest circular path on which cars can move has a radius of 119 m, while the largest has a radiusof 173 m, as the drawing illustrates. The height of the outer wallis 10.8 m. Find (a) the smallest and(b) the largest speed..

A candle is on the axis of a 15-cm-focal-length concave mirror, 36 cm from the mirror. Is the image real or virtual
The magnetic field of a plane-polarized electromagnetic wave is given by B=1.2*10^-6 Sin[2pi (z/240 – (t*10^7)/8)] in SI units . The field vector is B_ = B(z,t)[(i^+J^)/ 2^(1/2)]. Find the average power per square meter carried by the EM wave. Writ..
The velocity of a ball changes from m/s to m/s in 0.02 s, due to the gravitational attraction of the Earth and to air resistance. What is the rate of change of momentum of the ball
