ANSWER 1.42

Extracted text: 1.41 A rigid tank contains air at a pressure of 90 psia and a tem- perature of 60 °F. By how much will the pressure increase as the temperature is increased to 110 °F? 1.42 The helium-filled blimp shown in Fig. P1.42 is used at var- ious athletic events. Determine the number of pounds of helium within it if its volume is 68,000 ft' and the temperature and pres- sure are 80 °F and 14.2 psia, respectively. IFIGURE P1.42
