mass flow rates of these two fans? 1-45E The absolute pressure in a compressed air tank is 200 1-56 The basic barometer can be used to measure the height kPa. What is this pressure in psia? of a building. If the barometric readings at the top and at the bottom of a building are 675 and 695mmHg, respectively, 42 determine the height of the building. Take the densities of air Reconsider Prob. 1-58. Using appropriate softand mercury to be 1.18kg/m3 and 13,600kg/m3, respectively. ware, investigate the effect of the spring force in the range of 0 to 500N on the pressure inside the cylinder. Plot the pressure against the spring force, and discuss the results. 1-60 The piston of a vertical piston-cylinder device containing a gas has a mass of 60kg and a cross-sectional area of 0.04m2, as shown in Fig. P1-60. The local atmospheric pressure is 0.97bar, and the gravitational acceleration is 9.81m/s2. (a) Determine the pressure inside the cylinder. (b) If some heat is transferred to the gas and its volume is doubled, do you expect the pressure inside the cylinder to change? FIGURE P1-60 1-61 Both a gage and a manometer are attached to a gas tank to measure its pressure. If the reading on the pressure gage is 80kPa, determine the distance between the two fluid levels of the manometer if the fluid is (a) mercury (=13,600kg/m3) rIGURE 1-b6 or (b) water (=1000kg/m3).
