A 14-gram ovarian tumor is treated using a sodium phosphate solution in which
the phosphorus atoms are the radioactive Phosphorus-32 isotope with a half-life
of 14. 3 days and which decays via beta emission (RBE=1) with an energy of 1.71

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.
