Question
13 What is the pressure reading at sea level in the absolute (Pabs), atmospheric (Patm) and gauge (Pgauge) scales? Explain
14 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 How tall of a water column in inches equals 1 psig? Show Work
16 The density of seawater is 64 lbm/ft3. What is the specific gravity of seawater?
17 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?
18 29.9 inches of mercury provides 1 atmosphere of pressure. How many inches of mercury provides 1 psi of pressure?
19 408 inches of pure water provides 1 atmosphere of pressure. How many inches of water provides 1 psi of pressure?
20 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
Explanation / Answer
as per guidelines i can only answer one .Please raise different question for other one's.
16)64 lbm/ft3 in to kg/m^3
convert 1025.28kg/m^3
= (1025.28 kg/m3) (9.81 m/s2)
= 10057.9(N/m3)
= 10.057 (kN/m3)--answer
