Please help with the following problem and show work thank you 1. (40 pts) A spherical thermocouple (TC) is inserted into a duct to measure temperature of flowing air. The duct and TC were initially cold (27°C) and are exposed to sudden flow of hot air (77°C) at 3 m/s. a) (15 pts) What is the convective heat transfer coefficient on the TC surface? b) (15 pts) How long does it take for the TC to read the gas temperature...
Please help with the following problem and show work thank you 3. (20 pts) Preferred air duct shape: You are trying to decide whether to use a square or a round air duct to cool the air inlet temperature is 50 °C) through the duct. a) (5 pts) Write the expression for the convective heat transfer rate on the interior of the round duct (expand fully in terms of properties, not just non-dimensional terms, but do not calculate), b) (5...
(40 pts) Shell-and-Tube Heat Exchanger to make Jell-O Cups A counter-current shell-and-tube heat exchanger is used to heat Jell-O solution (water + gelatin) using saturated steam on the shell side. Jell-O solution must be heated to at least 80 oC, poured into individual plastic cups, and then cooled to make the solid Jell-O cups. The Jell-O solution is heated with steam that enters the shell at 2.0 bar (Tsteam = 120oC) and exits as a saturated liquid. At this temperature...
please show me the steps and the equations. I been failing this class and will award points to best answer (Extra) Water enters a smooth 2.66 cm diameter thin-walled pipe at a mean velocity of 1.8 m/s and a temperature of 20°C and is to heated by a hot fluid flowing past the outside of the pipe. The hot fluid is at a temperature of 50°C and the corresponding heat transfer coefficient on the outside surface of the pipe is...
Twenty [kw] of heat is to be removed from 375 [k] water flowing at 0.15 [kg/s] into the inner pipe of concentric tube heat exchanger. Cooling water enters the annulus at 290 [k] and leaves at 320 [k] with a flow in the opposite direction of the inner flow. The diameter of the thin- walled inner pipe is 2.5 [cm] a) b) c) Calculate the exit temperature of the hot fluid and the mass flow rate of the cold fluid...
please show work = To cool a summer home without using a vapor-compression refrigeration cycle, air is routed through a plastic pipe (k = 0.15 W/m-K, Di -0.15 m, Do-0.17 m) with a smooth interior surface that is submerged in an adjoining body of water. The water temperature is nominally at Too = 17°C, and a convection coefficient of ho- 1500 W/m2K is maintained at the outer surface of the pipe. Air from the home enters the pipe at a...
Please provide a step-by-step solution to this problem. Heat Transfer 1. The material should be from the textbook (Fundamentals of Heat and Mass Transfer) or similar 3. The annular pipe arrangement shown in the figure below is made of stainless steel and the outer surface is insulated. Air flows through the central pipe with a mass flow rate, ma0.026 kg/s. Water flows through the annular region with a mass flow rate, mw 0.58 kg/s. At the given position along the...
Can you please answer the following question 0. (CLO6 - 4 Marks) A counter-flow double-pipe heat exchanger is to heat water from 20°C to 80°C at mass flow rate of 1.5 kg's. The heating is to be accomplished by hot oil available at 150C at a mass flow rate of 2.5 kg/s. The inner tube is thin-walled and has a diameter of 1.5 cm with the length of 60 m. Fluid property: Fluid Type Mass flow rate, The Specific heat,...
Part II - Show your work (19 Marks] 16 Cold water (Cp = 4180 J/kg. "C) leading to a shower enters a thin-walled double-pipe counter flow heat exchanger at 15°C at a rate of 0.25 kg/s and is heated to 45°C by hot water (Cp = 4190 J/kg. "C) that enters at 100°C at a rate of 3 kg/s. If the overall heat transfer coefficient is 950 W/m2. C, determine the rate of heat transfer and the heat transfer surface...
Problem 3 (20 points) A cross-flow heat exchanger consists of a bundle of 32 tubes in a long duct. Hot water at 150°C and a mean velocity of 0.5 m/s enters the tubes having inner and outer diameters of 10.2mm and 12.5mm and has to be cooled to 136°C. The tubes are made of steel of thermal conductivity k-40 W/m.K. Air at 10°c enters the exchanger (unfinned) with a volumetric flow rate of 1.0 m3/s. The convective heat transfer coefficient...
