Answer with solution
A thick-walled cylinder tubing of hard rubber having an inside radius of 20mm is being used as temporary cooling coil in a bath. Ice water is flowing rapidly through inside tube and the inside wall temperature is 274.9K. The outside surface temperature is 297.1K. A total of 14.65W must be removed from the bath by cooling coil. How many m of tubing are required?
A saturated steam at 410K is being transported in a pipeline (brass drawing tubing) at a rate of 1 grams/second. Pipe has inside diameter of 0.025 m . The tube is 100m long. The pressure at the entrance is 80kPa. (use Perry's Handbook for the properties and constants) R = 8314J/kgmol.K; MW=18.02g/mol What is the a.) value of G in kg/s.m2? b.)value of friction factor? 3 significant figures c.)the % of pressure drop? d.)the outlet pressure? e.) compressible or not?
Heat transfer problem Water flows through a thin-walled cylindrical tube of diameter 1 cm, maintained at a uniform temperature, ?s = 360 K. The inlet and outlet temperature of water was found to be ?i= 280 K and ?o = 355 K, respectively. (a) What is the log mean temperature difference in this case? (b) If the mass flow rate is 0.005 kg/s, what is the total rate of heat transfer from the tube to the water? (c) What is the Reynolds number corresponding to the given flow conditions? (d) Assuming fully developed flow in the entire tube, what should be the length of the tube to allow the abovementioned operating conditions ?
48. Water is flowing in a smooth pipe of diameter D. A section of this pipe hav- ing a length of L is heated. Water at the inlet to the heated section has a tempera- ture of Tŋ. Water temperature at the exit of the heated section is Tp. The heated section of the pipe wall is maintained at a constant heat flux so that a constant temperature difference of AT, = T, – T, exists between the wall and the bulk wa- ter temperature. Show that for turbulent flow in the pipe and a specified heated length and pipe diameter, water temperature at the exit of the heated section is given by: 402 0.6 Pr T52 =Tf +0.0876 L AT DO.8 0.2 m

Only answer if you are 100% sure otherwise i will downvote... An ASTM B75 copper tube sheathes a heating element that is used to boil water at 1254 kPa. The copper tube is immersed horizontally in the water, and its surface is polished. The tube diameter and length are 5 mm and 9.5 cm, respectively. The maximum use temperature for ASTM B75 copper tube is 204°C. Determine the highest evaporation rate of water that can be achieved by the heater without heating the tube surface above the maximum use temperature. Use the property tables to calculate the properties of water at saturation temperature. The surface tension 0 at 190°C is 0.03995 N/m. Also, Csf 0.0130 and 10 for the boiling water on a polished copper surface. The highest evaporation rate of water is g/s?
