When you stand up on your feet your feet cover an area of about 0.2 m2. Your feet push on the ground with a pressure of 50 lbs for each foot . What is your weight? (Hint: Weight is a force. ) Use the formula Pressure = Force / Area to solve the following problems.

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.
