- Pls answer q3(as I am still not sure whether or not I did q2 correctly)A single-phase fluid reservoir is described by four equal blocks as. The reservoir is horizontal and has homogeneous and isotropic rock properties. k-270 md and -0.27. The gridblock dimensions are Ax-300 ft. Ay-350 ft, and h 40 ft. The reservoir fluid properties are B-B-1 RB/STB, p-50 lbm/ft, and μ-0.5 cP. The reservoir left boundary is kept at constant pressure of 4000 psia, and the reservoir right boundary is sealed off to flow. A 7-in vertical well was drilled at the center of gridblock 4. The well produces 600STB/D of fluid and has a skin factor of 1.5. Assuming that the reservoir rock and fluid are incompressible, find the pressure distribution in the reservoir and the FBHP of the well. Perform a material balance check.Water is entering a heated tube at mass ow rate of 1.2 kg/s. The temperature at the inlet is 20 C and at the outlet is 80 C.

During this process the total heat transferred to the gasis equal to the heat necessary to double the absolute temperature of the gas at constant volume. What is the maximumratioforthe volume increase? I do not understand why you can say that the first law of thermodynamics gives that the sum of work equals the sum of heat when the process is not isothermal. Therefore, setting work equal to heat in step 2 does not make sense to me. Could you please elaborate why this is valid? Additionally, why do we know that this is the maximum y? Doesn't the max y occur for an isobaric process? Thank you.

It is being heated by steam outside the pipe and steam film coefficient may be taken as 11 kW/m2°C. At a particular point along the pipe, the oil is at 50°C, its density is 880 kg/m³, its viscosity is 2.1 cP, its thermal conductivity is 0.135 W/m°C and its specific heat is 2.17 J/g°C. What is the overall heat transfer coefficient at this point, based on the inside area of the pipe? If the steam temperature is 130°C, what is the heat flux at this point, based on the outside area of the pipe?For a water flow over a steel surface, the temperature of water at a specific location was found to change with the vertical distance from the surface (y) up to a distance of 0.015 m as T(y) = 60 + 20y + tan(y), where temperature is in °C and y is in cm. The surface temperature and ambient temperature was measured as 60°C and 105°C, respectively. The thermal conductivity of steel and water are, respectively, 48 W/m-K and 0.6 W/m-K. What is the local convection coefficient at this location?
