Department of Chemical Engineering Winter, 2008 University of California, Santa Barbara CHE 110A Problem Set No. 2 Due Wednesday, January 16, 2008 Objective : to understand and perform calculations using fundamental mechanical relations in thermodynamics Problem 2. Smith, van Ness, Abbott, 1.5, page 16 Pressures up to 3,000 bar are measured with a dead-weight gauge. The piston diameter is 4 mm. What is the approximate mass in kg of the weights required? Problem 3. Smith, van Ness, Abbott, 1.7, page 16 The reading on a mercury manometer at 25 °C (open to the atmosphere at one end) is 56.38 cm. The local acceleration of gravity is 9.832 m s -2 . Atmospheric pressure is 101.78 kPa. What is the absolute pressure in kPa being measured? The density of mercury at 25 °C is 13.534 g cm -3 . Problem 4. Smith, van Ness, Abbott, 1.15, page 17 A gas is confined in a 1.25(ft)-diameter cylinder by a piston, on which rests a weight. The mass of the piston and weight together is 250(1b m ). The local acceleration of gravity is 32.169(ft)(s) -2 , and atmospheric pressure is 30.12(in Hg).
