1. Stabilized Crude oil with specific gravity of 0.82 and Kinematic viscosity of 4.1 Centistoke is flowing through a 6-inch S-40 pipe, 12.5km long at the rate of 230 GPM. Calculate the pressure drop across the entire length of the pipe.

2. A natural gas mixture consists of the following components;

- Methane (C
_{1}) = 75% - Ethane (C
_{2}) = 16% - Propane (C
_{3}) = 9%

Determine the specific gravity and average molecular weight of the natural gas mixture.

3. Using the CNGA equation, determine the compressibility factor of natural gas of specific gravity, 0.65 with average pressure of 500psig and gas temperature of 80

^{0}F.

4. A natural gas pipeline made of API 5L X42 14 - inch pipe (wall thickness of 0.5 inch) is 200km long. The inlet pressure is 90bar absolute, the outlet pressure is 20bar absolute and the average temperature is 25

^{0}F. The gas consists of the following components;

- Methane (CH
_{4}) = 78% - Ethane (C
_{2}H_{6}) = 19% - Propane (C
_{3}H_{8}) = 3%

Calculate the flow rate in Million cubic meter/day and MMSCFD using Weymouth and Panhandle B equations. (Use Z = 0.85 and E = 1.0)
