An oil well has a formation pressure of 2500 psi and a bubble point pressure of 2500 psi. A production test resulted an oil rate of 48 bpd and a water rate of 72 bpd at a measured Pwf of 2000 psi. Calculate the following and plot the results to create an IPR curve for this well.

a. The maximum oil, water and total fluid rate possible.
b. The oil, water and total production rate with a Pwf = 500 psi.
c. Determine the Water Cut (%) at Pwf test, Pwf = 500 psi and at Qmax total fluid.
d. Create the Inflow Performance Curves on a Pwf vs Q graph for this well.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?

At 12 noon, the count in a bacteria culture was 400; at 4: 00 pm the count was 1200 let p(t) denote the bacteria cou population growth law. find: (a) an expression for the bacteria count at any time t (b) the bacteria count at 10 am. (c) the time required for the bacteria count to reach 1800.
