A scuba diver makes a slow descent into the depths of the ocean. His vertical position with respect to a boat on the surface changes several times. He makes the first stop 9.0 m from the boat but has a problem with equalizing the pressure, so he ascends 3.0 m and then continues descending for another 12.0 m to the second stop. From there, he ascends 4 m and then descends for 18.0 m, ascends again for 7 m and descends again for 24.0 m, where he makes a stop, waiting for his buddy. Assuming the positive direction up to the surface, express his net vertical displacement vector in terms of the unit vector. What is his distance to the boat?

A soap bubble of radius 12 cm is blown. Surface tension of soap solution is 30 dyne/cm. calculate the work done is blowing the soap bubble.
Liquid water enters a 16-kW pump at 100-kPa pressure at a rate of 5 kg/s. Determine the highest pressure the liquid water can have at the exit of the pump. Neglect the kinetic and potential energy changes of water, and take the specific volume of water to be 0.001 m3/kg.
8. A belt conveyor is used to deliver a fluid to a reservoir, see the figure. The depth of the fluid film on the belt is such that the velocity on the free liquid surface of the film is zero. By considering only the work done by the belt on the fluid in shear, find the efficiency of this device. epart ani ity deof Engi.
An asteroid made out of iron (7860 kg/m3) strikes the Earth in an areawhere the oceans are very deep. The velocity of the asteroid upon impact isthe same for most debris hitting the Earth’s atmosphere, 30 km/s.The difference in potential energy from orbit to ground is negligible at thisspeed. Assuming that 80% of the asteroid’s kinetic energy is transferred toheating the water, what volume of water (assuming a density of 1000 kg/m3)will be vaporized? We will assume that the water is taken from 70o F tothe point that it becomes steam. Also, assume that the asteriod is spherical,with a radius of 750 m.
Water discharges from a large tank through a pipe 40 mm diameter and length of 55 m that is sharp at entrance. The level of water in the tank is 3 m above the centre end of the pipeline work. Consider all the minor losses and the co-efficient of friction (ƒ = 0.008) for the pipe. What is the potential head difference in the system?.
