Imagine that you and four of your classmates have measured the viscosity of engine oil and recorded the values shown in the accompanying figure. Determine the average, variance, and standard deviation for the measured viscosity of oil.
Determine the height h in m of substance X in the manometer. The height of the water is hw = 0.35 m. The specific gravity of the oil is 0.83, the density of the water used in the experiments is 998.2 kg/m3, the specific weight of substance X is 124 kN/m3. Indicate your answer to 3 decimal places.
In a relative density test, the following values are recorded:
Dry mass = 3017 g
Submerged mass = 1050 g
Saturated, Surface Dry (SSD) mass = 3033 g
Find the relative density values (RDapparent, RDbulk, and RDSSD) by first completing the phase diagram. (write answers in the phase diagram to the nearest whole number. Write the relative density answers to two decimal places.)
