MECH 371 Thermodynamics I Fall 1998 TEST #1 Name:. ................................................ Open book, closed notes Note: One of the answers given for each question is the right answer, rounded to some appropriate number of significant digits (usually 2 or 3). In the unlikely event that all the answers are wrong (due to an error in my solution), ignore the answers and simply write down your answer next to the question. Take the gravitational acceleration to be g = 9.8 m/s 2 , the density and specific heat of liquid water to be 1000 kg/m 3 and 4.18 kJ/kg. ° C, and the specific heats of air to be c v = 0.718 kJ/kg. ° C and c p = 1.0 kJ/kg. ° C 15% 1 The atmospheric pressures at the top and the bottom of a building are read by a barometer to be 96.0 and 98.0 kPa. If the density of air is 1.2 kg/m 3 , the height of the building is (a) 14 m (b) 17 m (c) 142 m (d) 170 m (e) 210 m 15% 2 A room is filled with saturated steam at 100 ° C. Now a 5-kg bowlind ball at 25 ° C is brought to the room. Heat is transferred to the ball from the steam, and the temperature of the ball rises to 100
