The pressure reading in a mercury barometer is 76 cm. Convert this into N/m^2. If a barometer were made with water of density 1.0 g/cc, what would be equivalent pressure reading in cm unit?
Homework Answers
P = rho * g h = 13.6* 10^3* 9.8* 0.76
P = 1.013* 10^5 N/m^2
=====
b)
P = h * ( rho *g)
h = 1.013* 10^5 / ( 1000* 9.8)
h = 10.336 m = 1033.6 cm

Comment before rate in case any doubt, will reply for sure.. goodluck

The column of mercury in a barometer stands 70.0cm high. How tall would the barometer have to be if the mercury were replaced by water? (the density of mercury is 1.36x10^4kg/m^3)

Mercury (Hg) can be used in a barometer to measure air pressure, based on how tall a column of mercury can be supported by the pressure of the atmosphere or another gas sample. The barometric reading a specific day was 743.8 mm Hg. If the interior circumference of the tube holding the mercury is 9.82 mm, what is the mass of mercury in the tube (above the pool of mercury)? The column may be treated as a cylinder. Mercury has...

Question 3. i. Define absolute pressure, gage pressure and vacuum pressure. ii. If a mercury barometer reads 720 mm Hg. Determine the atmospheric pressure in kPa and psi. (I psi -6.895 kPa. Density of Hg - 13.56 g/cc). Question 4 i. Define/explain energy, kinetic energy, potential energy and internal energy ii. Explain the contribution/mechanism of internal energy with sketch.

1. A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 699 mm Hg. Express this pressure in atmospheres, kilopascals, torrs, pounds per square inch, and pascals. Hint: 1 atm = 101.3 kPa = 760 torr = 760 mm Hg = 14.69 psi = 1.013×105 Pa mm Hg atm kPa torr psi Pa 699 2. An automobile tire is inflated to a pressure of 29.2 psi. Express this pressure in atmospheres, kilopascals, inches Hg,...
