Question
I The density of mercury changes approximately linearly with temperature as p = 13 595 - 25Tkg/m' (7 in Celsius), so the same pressure difference will result in a manometer
reading that is influenced by temperature. If a pressure difference of 100 kPa is measured in the summer at 35 C and in the winter at-15 C, what is the difference in column height between the two measurements?
