A tank measuring 21m*15m*16m has an ullage port extending 1 m above the top of the tank. It is to be loaded with crude oil at 23°C. 3% of the tank vol. is to be left for expansion when maximum temperature expected during the outage is 42°C. ( Density of oil =0.81@ 15°C in vacuum). Find the mass of oil loaded and ullage at load port. Given From ASTM tables- VRF for 23°C = 0.9929, VRF for 42°C = 0.9761, WRF = 0.81 – 0.0011 = 0.8089 Sir pls solve this question step by step as it would be great help for me. Awaiting for your replies.
