A large water tank empties slowly through a small hole under the force of gravity. The flow is steady, and the volumetric flow rate (in mụ/s) depends on the exit velocity V, the gravitational acceleration g, the depth of the water h, and the diameter of the hole D. (a) Express the nondimensional volumetric flow rate ġ in terms of its dependence on the other nondimensional groups. (b) A test is to be made on a 1/4th scale model. What is the ratio of the model volumetric flow rate to the prototype volumetric flow rate that wou

After the near spacecraft passed mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid eros, the final destination for the mission. after getting close to eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 × 10^3 m) around the asteroid. so much propellant had been used that the final mass of the spacecraft while in circular orbit around eros was only 545 kg. the spacecraft took 1.04 days to make one complete circular orbit around eros. calculate what the mass of eros must be.
