The nearest town to mount elbert is leadville at an altitude of 10,152 feet(3100 meters). in may, the average high temperature in leadville is about 13 degrees celsius. estimate the high temperature at the top of mount elbert in may.

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
