The absolute pressure inside the cylinder is now 500 kpa. ifa gauge were used to measure the gauge pressure inside the system in mm of mercury, what would it be? assume pmercury = 13595 kg/m3 and g = 9.80665 m/s2

Gauge pressure = 2990.32 mmHg

Explanation:

Step 1

Calculation of Gauge Pressure

Gauge pressure = Absolute pressure - Atmospheric pressure

Absolute pressure = 500 kPa = 500000 Pa

Atmospheric pressure = 101325 Pa

Gauge pressure = Absolute pressure - Atmospheric pressure

                            = 500000 - 101325

                             = 398675 Pa

Conversion of pressure in Pa to mmHg

P = ρgh

Where,

P = Pressure

g = Acceleration due to gravity = 9.80665 m/s2

ρ = Density of mercury = 13595 kg/m3

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
