3.57. The liquid level in a tank is determined by measuring the pressure at the bottom of the tank. A calibration curve is prepared by filling the tank to several known levels, reading the bottom pressure from a Bourdon gauge, and drawing a plot of level (m) vs. pressure (Pa). a. Would you expect the calibration curve to be a straight line? Explain your answer. b. The calibration experiment was done using a liquid with a specific gravity of o.900, but the tank is used to store a liquid with specific gravity of o.800. Will the liquid level determined from the calibration curve be too high, too low, or correct? Explain. c. If the actual liquid level is 8.0 meters, what value will be read from the calibration curve? If the tank has a height of 10.0 m, what value will be read from the curve when the tank overflows?

A calibration curve is prepared by filling the tank to several known levels, reading the bottom pressure from a Bourdon gauge, and drawing a plot of level (m) vs. pressure (Pa). a. Would you expect the calibration curve to be a straight line? Explain your answer. b. The calibration experiment was done using a liquid with a specific gravity of o.900, but the tank is used to store a liquid with specific gravity of 0.800. Will the liquid level determined from the calibration curve be too high, too low, or correct? Explain. c. If the actual liquid level is 8.0 meters, what value will be read from the calibration curve? If the tank has a height of 10.0 m, what value will be read from the curve when the tank overflows?
