Unformatted text preview: o C Express this temperature in R, K and o F. 7. (1-45) The maximum safe air pressure of a tire is typically written on the tire itself. The label on a tire indicates that the maximum pressure is 35 psi (gage). Express this maximum pressure in kPa. 8. (1-58) Consider a 70-kg woman who has a total foot imprint area of 400 cm2. She wished to to walk on snow, but the snow cannot withstand pressures greater than 0.5 kPa. Determine the minimum size of the snowshoe needed (imprint area of snowshoe) to enable her to walk on the snow without sinking. 9. (1-59) A vacuum gage connected to a tank reads 15 kPa at a location where the barometric pressure reading is 750 mm Hg. Determine the absolute pressure in the tank. Take r Hg = 13,590 kg/m3....
