Problem 1: Prolonged exposure to direct sunlight can cause material in pipe to
heat up. Assume the following scenario: two block valves in a pipeline are closed,
trapping liquid propane inside. Throughout the day, solar radiation increases the
liquid propane temperature from 10 °C to 25 °C. The liquid was had an initial
pressure of 10 bar. How much of a pressure increase can we expect from this
temperature change?
(Alternatively, external fire to the pipeline can cause temperature change)
