Carbon dioxide (CO:) is used for the gas cooled reactor in shell and tube heat exchanger type steam generator (shown in Figure 2). 90000 kg/h entered to the exchanger under pressure and temperature of 4 bar and 500 °C respectively. The steam saturation temperature is 250 °C when the carbon dioxide leave the generator at 330°C. Presume the formed steam is saturated and dry. Using 25 mm inner diameter and 2 mm wall thickness, a copper tube is designed for CO; mass flow rate of 350000 kg/m'h. Neglect the thermal resistance of the steam side. (a) Determine number of tubes that should be used (b) Determine the length of the tubes Take the following properties for the carbon dioxide: Cp=1.172 KI/kg °C; u=0.0000298 Ns/m²; k=0.043 w/m °C; p=3.26 kg/m² Take k (Copper) = 384 W/m °C Water in (cold fluid) - 250°C CO, (hot fluid) in (f = 500°C) CO, out (2 - 330°C) Steam out (2 250°C)

In a gas manufacturing plants, they presented a horizontal tube in which a gas assumed to be ideal is flowing steadily. It was identified that no heat and work interaction was done. Also, there is a significant changes in the pipe diameter as well as velocity. If in case we select N2 as the flowing gas at 761.67 R at a velocity of 5.6 m/h, Calculate the temperature where the velocity us 180 km/h? Assume cp=7/2 R.
2. Engine oil (similar to oil C) flows at 1.2 ft/s through a 1-inch diameter tube. The bulk oil temperature is 190 F and the tube surface temperature is 210 F. Determine the unit convective coefficient for a tube length of 10 ft. If the tube length is doubled, what is the percentage increase (or decrease) in the film coefficient? Let k = 0.96 Btu-in/hr-ft2-F and c = 0.52 Btu/lb-F for the oil. *

a film-type condenser consists of a packed bed of 3-cm diameter spheres with a voidage of 35%. water sprayed onto the bed at 60oC is used to condense steam entering at the base at a saturation temperature of 100oC. How deep must the bed be to ensure complete condensation of the steam, and what is the outlet temperature of the water? (Use water properties based on the mean of the inlet and outlet water temperatures, and iterate if necessary)
