The rectangular gate shown in section is 3 m long (perpendicular to the paper) and is hinged about its upper edge B. The gate divides a channel leading to a fresh-water lake on the left and a salt-water tidal basin on the right. Calculate the moment, M, on the shaft of the...
The resistance value of a thermistor at a specified temperature with negligible electrical power to avoid self heating. Usually base resistance will be defined at 25 °C.
Its a NTC looking shape
I think Y is resistance
X is temp.
Not sure
At 100C: R= 0.08
Could I plug in 25 C and solve for Y?? .
Using the regression eqn. Find the base resistance of the thermistor.
Find the temp. Of the boiling water using this eqn.
Y=1.54e^-0.059x
How do I go about solving this problem
