A finned tube cross flow heat exchanger with inlet and outlet temperatures of hot and cold fluids. LatexU 100 Wm2Klatex Hot gas side. Hot exhaust gases which enters a finned-tube cross-flow heat exchanger at 300C and leave at 100 C are used to heat pressurized water at a flow rate of 1 kgs from 35 C to 125 C.
Hot exhaust gases 15 kgs enter a finned-tube cross-flow heat exchanger at 250C and is used to heat pressurized water at a flow rate of 1 kgs available at 35C. Exhaust gas specific heat is 1000 JkgK and water specific heat is 4197 JkgK. Overall heat transfer coefficient is.
Ii Hot exhaust gases which enters a finned tube cross flow heat exchanger at 300C and leave at 100C are used to heat pressurized water at a flow rate of 1 kgs from 35 to 125C. The exhaust gas specific heat is approximately 1000 JkgK and the overall heat transfer co-efficient based on the gas side surface area is Uh 100Wm 2 K. Determine the required gas side surface area using the NTU.
A single-pass cross-flow heat exchanger uses hot exhaust gases mixed to heat water unmixed from 30 to 80C at a rate of 3 kgs. The exhaust gases having thermo physical properties similar to air enter and exit the exchanger at 225 and 100C respectively. The finned tube consists of a round pipe with attached fins which maximize surface area and heat transfer rates.
Liquid flows through the tubes and receive heat from hot gases flowing across the tubes. A finned tube exchanger where boiler exhaust gases are used for feed water preheating is generally referred to as a boiler economizer. Exhaust gas passes over the other side of the recuperator at exhaust temperatures ranging from 750 to 1000 F.
Compressor air temperatures are now. The exhaust gases enter the heat exchanger at 400C at a rate of 32 kgmin while water enters at 15C. The heat exchanger is not well insulated and it is estimated that 10 percent of heat given up by the exhaust gases is lost to the surroundings.
If the mass flow rate of the exhaust gases is 15 times that of the water determine. This problem often presents itself in the muffler where the exhaust gases are not hot enough to vaporize water deposits. This problem is seen more in areas experiencing high rainfall and snow.
If you have been driving a lot off-road or encounter potholes it can cause strain on the exhaust.
