1. The pump in the boat shown pumps 6 ft3 /s of water through a submerged water passage, which has an area of 0.25 ft2 at the bow of the boat and 0.15 ft2 at the stern. Determine the tension in the restraining rope, assuming that the inlet and exit pressures are equal.
2. Oil (sp. gr. = 0.8) flows smoothly through the circular reducing section shown at 3 ft3 /s. If the entering and leaving velocity profiles are uniform, estimate the force which must be applied to the reducer to hold it in place.
