The specification of a pressure sensor is shown below: Range of measurement: 10 psi to 250 psi. Accuracy : ±0.2% of span. Transfer function : 0.5?/psi. Transfer function accuracy: ±0.1% Sensor output resistance, R : 2k? - 20k?. Sensor time constant: 200 ms
. The resistance is then converted to a voltage with the transfer function:
V= 10R/R+1000
1/Determine the uncertainty for measurement of 120psi. What is the possible pressure?
2/Determine the possible range of the transfer function. Interpret the possible range that you have determine.
3/Determine the linear relationship between resistance and pressure. Draw a graph and explain briefly why it should be linear relationship.
4/Determine the pressure result from a resistance of 10 k?.
5/At t = 0 s, the pressure change suddenly from 12 psi to 120 psi. Determine the voltage output and its pressure at 0.24 s. At what time the output reach 0.3V?

Consider the reaction shown below.
PbCO3(s) PbO(s) + CO2(g)
Calculate the equilibrium pressure of CO2 in the system at the
following temperatures.
(a) 210°C atm = _______ atm
(b) 480°C atm = _______ atm
Note: To find the value of the
equilibrium constant at each temperature you must first find the
value of G0 at each temperature by using the equation G0 = H0 -
TS0. For this reaction the values are H0 = +88.3 kJ/mol and S0=
151.3 J/mol*K
