Consider a shell-and-tube heat exchanger. Air with a flow rate
of
1.5 kg/s at 500°C and at atmospheric pressure flows through
200
parallel tubes. Each tube has an internal diameter of 2 cm
and
length of 4 m. Assume that the D/D0 = 0.5 data can be used
for
the contraction and enlargement. The outlet temperature of
the
cooled air is 100°C. Calculate the pressure drop for
a. The abrupt contraction
b. Friction
c. Acceleration
d. Enlargement
and compare the total pressure drop with the frictional
pressure
drop.
Homework Answers
here mainly the pressure drop
is due to friction only we can compare it with the answer too.

A shell and tube heat exchanger with one shell pass and two tube passes is used to heat 8.82 kg/s of fluid from 15.6 °C to 60 °C by using saturated steam at 150 kPa. The steam is condensing on the outside of the tubes with h= 15 kW/m2.K. There are 50 tubes with an outside diameter of 1.91 cm and a wall thickness of 0.211 cm. If the fouling coefficient on the inside of the tubes is 5678 W/m2.K,...

A shell and tube heat exchanger with one shell pass and one tube pass will be used to condense the steam to saturated liquid, which enters the shell side as a saturated vapor at 400 K. The tube side contains R-134a refrigerant with an inlet temperature of 300 K and a mean velocity of 0.4 m/s. The steam flow rate is 1.5 kg/s. The tubes are made from AISI 302 stainless steel and have a 1" nominal diameter (Di =...

1. A shell-and-tube heat exchanger with 1 shell and 10 tubes is used to heat glycerine in the shell, with hot water in the tubes. The tubes are thin walled and have a diameter of 1.5 cm and length of 2 m. The water enters the tubes at 100°C at a rate of 5 kg/s and leaves at 55°C. The glycerine enters the shell at 15°C and leaves at 55°C. Determine the mass flow rate of the glycerine and the...

Q2. Shell-and-tube heat exchangers with hundreds of tubes housed in a shell are commonly used in practice for heat transfer between two fluids (shown in Figure 1). Such a heat exchanger used in an active solar hot-water system transfers heat from a water-antifreeze solution flowing through the shell and the solar collector to fresh water flowing through the tubes at an average temperature of 60°C at a rate of 15 L/S. The heat exchanger contains 80 brass tubes 1 cm...

Water flowing at a rate of 10 kg/s through 50 tubes in a double-pass shell-and-tube heat exchanger heats air which flows on the shell side. The tubes are bras with outside diameter of 2.6 cm and are 6.7m long. The heat transfer coefficients on the inside and outside tube surfaces are 470 W/m2K and 210 W/m2K, respectively. Air enters the unit at 15°C with a flow rate of 16 kg/s. The entering water temperature is 350K. A) Draw and label...
