Problem X3-5, Heat Transfer, Spring 2018 A single-pass, double-tube counterflow heat exchanger will be used to heat a 0.14 kg/s stream of water nowing in the 12-mm diameter inside tube. The water in the inside tube enters the heat exchanger at 25 C. The water will be heated with a 0.12 kg/s m of hot water flowing in the annulus between the inside and outside tube that enters the heat exchanger at 80°C. UP the hot and cold streams, and...

A counter-flow heat exchanger is stated to have an overall heat transfer coefficient of 284 W/m2.K when operating at design and clean conditions. Hot fluid enters the tube side at 101°C and exits at 71°C, while cold fluid enters the shell side at 27°C and exits at 42°C. After a period of use, built-up scale in the heat exchanger gives a fouling factor of 0.0004 m2 K/W. The surface area is 93 m². Assume both hot and cold fluids have...

Hot and cold water streams exchange heat in a double pipe heat exchanger in counter current flow. The pipes are 3 ft long. The inside pipe is a 5/8 inch BWG 12 copper tube. The outside pipe is a 1 inch Sch 40 steel pipe. The outside pipe is insulated to minimize heat loss to the surroundings. The hot water enters the inside tube at 180F with a flow rate such that Re = 10000 The cold water flows through...

Hot water flows thorough a parallel flow heat exchanger at a rate of 10 kg/min and is cooled by a cold water stream of flow rate 25 kg/min. The inlet temperatures of hot and cold water streams are 70 oC and 25 oC, respectively. The outlet temperature of the hot water is expected to be 50 oC. The individual convective heat transfer coefficient on both sides of the heat transfer area is 600 W/m2 .K. Take the specific heat for...

11.32 A single-pass, cross-flow heat exchanger uses hot exhaust gases (mixed) to heat water (unmixed) from 30 to 80°C at a rate of 3 kg/s. The exhaust gases, hav- ing thermophysical properties similar to air, enter and exit the exchanger at 225 and 100°C, respectively. If the overall heat transfer coefficient is 200 W/m2.K, estimate the required surface area. 11.33 Consider the fluid conditions and overall heat transfer coefficient of Problem 11.32 for a concentric tube heat...

at Your objective in this problem is to design a "simple" annular flow heat exchanger (see the "simple" description the beginning of this HW). A heat exchanger of this kind can easily be built in your garage with two different size pper pipes along with some solder. Assume both fluids are water with the cold fluid flowing in the outer tube. The pipe diameters are based in Type L copper tube dimensions: outside diameter 1/2 -inch nominal tube is 0.625...

Consider a cross-flow heat exchanger with a surface area of 10 m². The cold fluid has a heat capacity rate of 2310 W/K and inlet and outlet temperatures of 25°C and 150°C respectively. The hot fluid has a heat capacity rate of 2000 W/K and an inlet temperature of 325°C. If the cold fluid can be considered mixed and the hot fluid unmixed, find the overall heat transfer coefficient, u, in W/m2.K, and the outlet temperature, in °C, of the...

A shell-and tube heat exchanger has one-shell pass and 2-tube passes. This heat exchanger is used to cool oil, flowing through the tube-side from 140°C to 50°C. The cooling is accomplished by water, flowing through the shell-side, which enters the heat exchanger at 15°C and leaves at 32°C. Each tube pass consists of 60, 2.54-cm-O.D. tubes with a wall thickness of 1.65 mm.if the inside and outside heat transfer coefficients are h1=260 W/(m^2°C) and h°=970 W/(m^2°C), respectively, and the fouling...
