A pump is used to circulate hot water in a home heating system. Water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. The inlet pressure and temperature are 14.7 Ibf/in.?, and 180°F, respectively; at the exit the pressure is 60 lbf/in.? The pump requires 1/35 hp of power input. Water can be modeled as an incompressible substance with constant density of 60.58 Ib/ft³ and constant specific heat of 1 Btu/lb · °R. Neglecting kinetic and potential energy effects, determine the temperature change, in °R, as the water flows through the pump. AT = i °R

During the summer after your first year at Carnegie Mellon, you are lucky enough to get a job making coffee at Starbucks, but you tell your parents and friends that you have secured a lucrative position as a 'java engineer.' An eccentric chemistry professor stops in every day and orders 250 ml of house coffee at precisely 95*C. He then adds enough milk at 4*C to drop the temperature of the coffee to 90*C. Calculate the amount of milk, in ml, the professor must add to reach this temperature. Show all of your work including equations and units. Assume coffee and milk have the same specific heat capacity of 4.186 J/g*C and density of 1.0 g/ml.

The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25°C, the pressure gage reads 210 kPa. If the volume of the tire is 0.025 m³, determine the pressure rise in the tire when the air temperature in the tire rises to 50°C. Assume the atmospheric pressure to be 100 kPa and gas constant of 287 J/(kg-K).
