Practice every matching question in batches of 20, with every available option.
An oil emulsion having 15% water cut by weight is being treated in a horizontal heater-treater unit at the rate of 6000 kg/hr. The inlet temperature of the emulsion is 30°C and operating temperature of the heater-treater is 40°C. The specific heat capacity of water and oil are 1 kcal/kg°C and 0.5 kcal/kg°C, respectively. Assuming 10% of the total heat input is lost to the surroundings, the total heat energy required to break the emulsion in the heater-treater unit is ______ kcal/hr. (write answer with one decimal place)

Identify the CORRECT match for the flow regimes (Group 1) with the corresponding slopes of the pressure derivative (Group 2) used in the type curve analysis.
| Flow Regime (Group 1) | Pressure Derivative Slope (Group 2) |
|---|---|
| I. Spherical flow | P. 1 |
| II. Linear flow | Q. 1/4 |
| III. Bilinear flow | R. -1/2 |
| IV. Boundary dominated flow | S. 1/2 |
