In the check your learning section of example 27.1, the author commented that even at z = 0.2, there is already an 11% deviation between the relativistic and the classical solution. what is the percentage difference between the classical and relativistic results at z = 0.1? what is it for z = 0.5? what is it for z = 1?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
