Graph, on a single hs plot, the isotherm for propane at 20°c and the isobar for propane at 1 bar.
use the data to estimate the slopes of each curve at the point where they cross. that is, numerically estimate \left(\frac{\partial h}{\partial s}\right)_t(∂h∂s)t and \left(\frac{\partial h}{\partial s}\right)_p(∂h∂s)p at 20°c, 1 bar.
h=517.6 kj/kg s=2.194 kj/kg-k
in the slides, i stated that \left(\frac{\partial h}{\partial s}\right)_p(∂h∂s)p = t. prove that this is true. compare this value to the answer estimated from the data.
note: i am not asking you to do \left(\frac{\partial h}{\partial s}\right)_t(∂h∂s)t because it is much more difficult than you are expected to be able to do at this stage.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
