33. Calculate, in kPa, the pressure exerted by a column of water that is 10-m tall. Assume the weight density of water to be 10,000 N/m3 , and ignore the pressure due to the atmosphere. 35. The depth of water behind the Hartebeespoort Dam is 220 m. Show that the water pressure at the base of this dam is 2200 kPa. 36. The top floor of a building is 20 m above the basement. Show that the water pressure in the basement is nearly 200 kPa greater than the water pressure on the top floor. 37. Calculate the average force per nail when Sara, who weighs 50 kg, lies on a bed of nails and is supported by 600 nails (see Figure 13.2). 38. Suppose that you balance a 5-kg ball on the tip of your finger, which has an area of 1 cm2. Show that the pressure on your finger is 50 N/cm2, which is about 500 kPa.
