A bus travels between two cities, but visits six intermediate cities upon the route. The means as well as standard deviations of the travel times are as follows:
A circular hole of 1.10 cm in diameter is cut in the side of a big water tank, 25.0 m beneath the water level in the tank. The top is open to the air. Compute (i) the speed of efflux; (ii) the volume flow rate.
Determine the magnitude of the water velocity at this point when the volume flow rate is 0.600 m^3/s ? (ii) At a second point in the pipe the water velocity consists of a magnitude of around 15.0 m/s. Determine the radius of the pipe at this point
