i need to vargonen of it one for me and the other for my classmate 

 

 

4(6)     An object on earth has a mass of 45 lbm. What is its weight on earth? Assuming that         gravity on the moon is 1/6th that of earth. What is its mass and weight on the surface of   the moon? Show Work

 

5(5)     An object has a density of 0.0136 lbm/ft3. If it has a mass of 3.25 lbm, what is the volume            of the object? What is the specific volume of the object? Show Work

 

6(5)     The specific gravity of water at 60°F is 1.000. If the temperature is raised to 100°F, what             happens to the value of specific gravity? Explain

 

 

 

 

13(10)What is the pressure reading at sea level in the absolute (Pabs), atmospheric (Patm) and        gauge (Pgauge) scales?  Explain

 

14(8)   A 30 foot tall water tower open to atmosphere is full of pure water. What is the pressure             at the bottom of the tower and at the halfway point in absolute and gage pressure? Show    Work

 

15(5)   How tall of a water column in inches equals 1 psig? Show Work

 

 

 

 

17(8)   An open tank full of water 10 feet tall and 18 feet in diameter has a pressure gauge at the   top and at the bottom of the tank. What are the psig readings on each of these gauges?

            Show Work

 

18(6)   29.9 inches of mercury provides 1 atmosphere of pressure. How many inches of mercury             will provide 1 psi of pressure? Show Work 

 

19(6)   408 inches of pure water provides 1 atmosphere of pressure. How many inches of pure    water provides 1 psi of pressure? Show work

 

20(18)Convert the following: (Use conversion factors below as needed).

            14.7 psia = 408 inches of water

            14.7 psia = 29.9 inches of mercury

            atm is abbreviation for atmospheres

           

            5 psiv to psig

 

            2 atm to psia

 

            12 inches of H2O to inches of mercury

 

            10 psi to inches of mercury

 

            Absolute zero pressure to psia

 

            0 psig to atm
