Question

Pressure Exercise Problems 1. (I) Estimate the pressure needed to raise a column of water to the same height as a 46-m-tall pine tree. 2. (I) Estimate the pressure exerted on a floor by (a) one pointed heel of area \( =0.45 \mathrm{~cm}^{2} \) and \( (b) \) one wide heel of area \( 16 \mathrm{~cm}^{2} \) Fig. 10-48. The person wearing the shoes has a massof \( 56 \mathrm{~kg} \). 3. (I) What is the difference in blood pressure \( (\mathrm{mmHg}) \) between the top of the head and the bottom of the feet of a \( 1.75 \mathrm{~m} \) tall person standing vertically? 4. (I) a. Calculate the total force of the atmosphere acting on the top of a table that measures \( 1.7 \mathrm{~m} \times 2.6 \mathrm{~m} \). b. What is the total force acting upward on the underside of the table? 5. How high would the level be in an alcohol barometer at normal atmospheric pressure? ( \( \rho_{\text {alcohol }}=0.79 \times 10^{3} \mathrm{~kg} / \mathrm{m}^{3} \) )
