Heat exchange between oil and water. water is flowing at the rate of 1.13 kg/s in a 1-2 shell-and-tube heat exchanger and is heated from 45°c to 85°c by an oil having a heat capacity of 1.95 kj/kg. k. the oil enters at 120°c and leaves at 85°c. calculate the area of the exchanger if the overall heat-transfer coefficient is 300 w/m2.k.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
