1. The specific weight of a fluid is 11 200 N=m3. Calculate the mass contained in 2 m3
(a) Using the standard gravity.
(b) Using the maximum gravity on the earth's surface.
(c) Using the minimum gravity on the earth's surface. 2. The specific gravity of mercury is given by the formula - SHg ¼ 13:620:0024T where the temperature is in degrees Celsius. What is the specific weight of mercury at 45-C? Calculate the error if SHg ¼ 13.6 were used at 45-C.
