A barrel of oil is around 159dm3. What is the mass of a medium crude barrel of oil in the average density is around 895Kg/m3?
159Kg
142Kg
142,000Kg
178Kg
Homework Answers
Solution:-
Volume = 159 dm3 = 0.159 m3 (1 dm3 = 1 × 10-3 m3)
Density = 895 kg /m3
Mass = ?
Density = Mass / Volume
or, Mass = Volume × Density
or, Mass = (0.159 × 895) kg = 142.3 kg
---------------------------------------------------------------
Hence, 142 kg should be the right answer.....

32. Saudi Crude Oil Supply: Low Prices For crude oil prices of at most $20 per barrel the supply by Saudi Arabia can be approximated by q = 0.34p + 1.2 million barrels per day (12 = p = 20), where p is the price per barrel.84 Calculate the price elastic- ity of supply when the price of oil is $15 per barrel. What does the answer tell you about Saudi oil production?

The oil derrick has drilled 5 km into the ground before it strikes a crude oil reservoir. When this happens, the pressure at the well head A becomes 25 MPa. Drilling "mud" is to be placed into the entire length of pipe to displace the oil and balance this pressure. Assume all pressures are gage pressures (Figure 1) ▼ Part A What should be the density of the mud so that the pressure at A becomes zero? Density of crude...
