12. A mixture of oil and gas flows through a horizontal pipe with an inside diameter of 150 mm. The respective volumetric flow rates for the oil and gas are 0.015 and 0.29 m³s¹. Determine the gas void frac- tion and the average velocities of the oil and gas. The friction factor may be assumed to be 0.0045. The gas has a density of 2.4 kgm-³ and viscosity of 1 x 10-5 Nsm 2. The oil has a density of 810 kgm-³ and density of 0.82 Nsm-2. Answer: 0.79, 20.8 ms-¹,4 ms-1
You would like to use a pipe-based continuous flow hydroponic system. In this configuration, the roots of the strawberry plants are exposed to water that flows continuously through cylindrical pipes, driven by a pressure pump. The pipes are oriented horizontally so that the nutrient-containing water flows in the axial (x) direction. You are wondering whether this design is sufficient to support the needs of your strawberry plants. Your hydroponics system requires you to pay for the costs of the electricity used to heat the water that flows through the pipes. Strawberry plants grow best when their roots are exposed to water at a temperature of 25°C. The water that flows through the pipes is stored in a tank (inside height = 2 m), which sits on the ground outside of a greenhouse. In July, the average air temperature is Tair = 26°C, with heat transfer coefficient hair = 20 W/m2·K. The temperature of the ground underneath the water tank is Tground = 10°C. The heat capacity of water is…
3.21 You must cool 78 kg/min of a 60%-by-mass mixture of glycerin in wa- ter from 108°C to 50°C using cooling water available at 7°C. Design a one-shell-pass, two-tube-pass heat exchanger if U = 637 W/m²K. Which side should the water flow through? Explain any design decision you make and report the area, TH₂0out and any other relevant features.
The clean U for an exchanger is 770 BTU/(hr 0 F ft2). Its tube area is 550 ft2. After operating for several months, it is heating water from 40 0F to 150 0F at a flow rate of 200 GPM with a heating fluid on the shell entering at 300 0F and exiting at 170 0 F. Has the overall U decreased significantly? how many 1.0 inch diameter, 20 ft long tubes would it take to equal the 550 ft2 area?
Pure water flows through the cross section of the pipe 0.3m long and 3cm in diameter. The water entering the pipe has a flow rate of 373 K, 0.2 MPa to 2 kg/s. The discharged water also has a flow rate of 2 kg/s. At this time, the temperature is 373 K and the pressure is 0.195 MPa. Under this condition, the density of water is 961.5 kg/cm3. Find what was done at the entrance and exit of the pipe (J/s). Pay attention to the sign.
4. The following heat exchanger uses 10 kg/s of hot air to heat and boil liquid water into saturated steam at 500 kPa. (a) Find the steam flow (kg/s) (b) Determine whether the process is allowed by the second law (Answer: It is not!) (c) On the surface, the process looks OK as Tair>Twater at both the inlet and outlet. You should be able to see the problem if you sketch the air and the water temperature profiles as you move left to right through the exchanger. (Hints: The air will be essentially a straight line, while the water will not. For the water, think about what happens when it is changing phase.) This is called a pinch point violation, and it is a very important design consideration in advanced combined cycle systems and in nuclear power plants. Air 100 kPa 160°C 10 kg/s Saturated Vapor 500 kPa Air: 160°C Steam: 151.8°C Q Air 100 kPa 30°C Liquid Water 500 kPa, 20°C Air: 30°C Water: 20°C
6. A heat exchanger was installed purposely to cool 0.50 kg of gas per second. Molecular weight is 28 and k=1.32. The gas is cooled from 150 deg C to 80 deg C. Water is available at the rate of 0.30 kg/s and at a temperature of 12 deg C. Calculate the exit temperature of the water.
All properties should be evaluated at the temperature of the steam.Saturated, pure steam at 65 ºC condenses on the surface of a vertical tube with outersurface diameter 2 cm which is maintained at a uniform temperature of 35 ºC. Determinethe tube length for a condensate flow rate of 5 x 10-3 kg/s.

It enters at 152 and leaves at 30°C.It the Steam flow rate is 1.25 kg/min, determine the dryness r fraction of Steam as it enters the condenser.
