Could you please do a unit analysis on Riedel and Antoine
equation to determine the units of the empirical coefficients.
Pressures in kPa and temperatures in Kelvin.
Riedel equation : lnP(T) = Ar + Br/T + Cr.ln(T) + Dr.T6
Antoine equation: lnP(T) = Aa - Ba/(Ca+T)
Given the equation:
sin(x+y)=x+cos(y)
a) Differentiate y with respect to x
b) Give the equation of the line tangent to the curve of at the
point (0,π/4)
Please show how calculus can be used in respect to measuring the
change of current or wave over a circuit. Please explain how the
problem works and what is happening at each step.
For the following, you can either provide a vector equation for
the curve, or you can describe the curve in words with sufficient
details.
a) Describe a curve that has curvature zero.
b) Describe a curve that has torsion zero.
c) Describe a curve that has constant nonzero curvature.
d) Describe a curve that has constant nonzero torsion.
e) Describe a curve that has zero curvature and zero torsion.
The resistance-temperature relationship of an NTC thermistor
can be approximately described using the following equation:
R(T)= a*exp(B/T), a=0.1865 & B=2,946K
Design a voltage divider as the signal conditioning circuit
for the negative temperature coefficient thermistor. Your circuit
should use a 5v power supply. It should produce a positive voltage
signal with a reading of approximately 4v at 100 degrees Celsius
and the lower readings at lower temperatures. Draw the circuit
schematic. Use the symbol for an adjustable resistor to represent...
Calculate the equilibrium vapor phase composition of a liquid hexane–water mixture at 50 °C, assuming that hexane and water are completely immiscible. The vapor pressures of the pure components can be described by the Antoine equation:
