A typical value for this ratio for a human would be 120/70, where the pressures are in mm Hg. As shown in Video V2.1, such pressures are commonly measured with a mercury manometer. What is the static pressure at a fire hydrant that is connected to the standpipe and located at ground level? Express your answer in psi.Ģ.2 Blood pressure is usually given as a ratio of the maximum pressure (systolic pressure) to the minimum pressure (diastolic pressure). The lab-type problems can be accessed by clicking on the "click here" segment of the problem statement.Ģ.1 The water level in an open standpipe is 80 ft above the ground. In the E-book, access to the videos that accompany problems can be obtained by clicking on the "video" segment (i.e., Video 2.3) of the problem statement. In the E-book, answers to the even-numbered problems can be obtained by clicking on the problem number. There is not a unique answer to these problems. Problems designated with a (t) are "open-ended" problems and require critical thinking in that to work them one must make various assumptions and provide the necessary data. Problems designated with an (*) are intended to be solved with the aid of a programmable calculator or a computer. Note: Unless otherwise indicated use the values of fluid properties found in the tables on the inside of the front cover.
