Abstract
The data from a tank thermal expansion experiment were treated by applying corrections to bubbler tube differential pressure measurements at the initial temmperature. The tank had a capacity of 3.55 m3 and an internal height of 8.70 m. Water was used as the experimental fluid and the masses of water for the 4 experimental runs were 911.1, 1497.3, 876.98, and 2048.3 kg. Initial temperature ranged from 13.5 °C to 37.6 °C; maximum temperatures ranged from 54.7 °C to 70.4 °C. Four corrections were calculated for each temperature to calculate the correction to calculate the differential pressure for each succesive temperature. The calculated differential pressure was compared to the measured differential pressure. The agreement between calculated and measured differential pressure was excellent.
