The prevailing atmospheric pressure on a plateau in Colorado is 0.706 atm. Express this pressure in pounds per square inch, kilo
noname [10]

Answer:

1. 10.37114 psi

2. 71.5178 KPa

3. 71517.8 Pa

4. 536.56 mmHg.

5. 21.12352 inHg

Explanation:

From the question given,

Pressure = 0.706 atm

The pressure in other units of measurement is obtained as follow:

1. Pressure in Psi

1 atm = 14.69 psi

Therefore, 0.706 atm = 0.706 x 14.69 = 10.37 psi

2. Pressure in KPa

1 atm = 101.3 kPa

Therefore, 0.706 atm = 0.706 x 101.3 = 71.5178 KPa

3. Pressure in Pa

1 atm = 1.013x10^5 Pa

Therefore, 0.706 atm = 0.706 x 1.013x10^5 = 71517.8 Pa

4. Pressure in mmHg

1 atm = 760mmHg

Therefore, 0.706 atm = 0.706 x 760 = 536.56 mmHg

5. Pressure in inHg

1 atm = 29.92 inHg

Therefore, 0.706 atm = 0.706 x 29.92 = 21.12352 inHg
