A 2.0 kg bar of copper is heated at atmospheric pressure so that its temperature increases from 20°C to 50°C. (a) What is the work done on the copper bar by the surrounding atmosphere? SOLUTION Conceptualize This example involves a solid, whereas the preceding two examples involved liquids and gases. For a solid, the change in volume due to thermal expansion is very small. Categorize Because the expanslon takes place at constant atmospheric pressure, we categorize the process as isobaric...

(c) Fuel oil, with a density of 870 kg m-, is pumped through a horizontal pipe, as shown in Figure Q2.2. The pipe is 100 mm in diameter and contains an orifice plate with a throat diameter of 40 mm. The pressure drop across the orifice is measured on a U-tube manometer, containing mercury with a specific gravity 13.6. The difference in levels of the columns is measured as 45 mm. The coefficient of discharge for the orifice plate Ca...
