The inner tube of atyer contains18 litres of air at
atemp of 10 c and apressure of 1.616×100000 if we heat thetube to35
c its volume increases to19 litres what will be the pressure
then?
Air at 30 C flows at 10 m/s across an in-line tube bank consist
of 5 rows with 10 tubes per row. The diameter of the tube is 5 cm
and the tube pitch is 13 cm. Water flowing in tube maintains the
tube surface temperature at 80C find the following:
a) the air temperature at the outlet of the tube
b) the convective heat transfere per unit length per tube to the
air
( it is heat transfer problem...
A solar collector design consists of an inner tube enclosed
concentrically in an outer tube that is transparent to solar
radiation. The tubes are thin walled with inner and outer diameters
of 0.08 and 0.10 m, respectively. The annular space between the
tubes is completely enclosed and filled with air at atmospheric
pressure. Under operating conditions for which the inner and outer
tube surface temperatures are 80 and 30°C, respectively, what is
the rate of convective heat loss per meter...

Air flows through this tube at a rate of 1400cm3/s . Assume that
air is an ideal fluid.
What is the height h of mercury in the right side of
the U-tube?
You are pumping up a road bicycle tire with a compressor. The
inner tube is initially completely deflated, and you inflate it to
a final pressure of 120psig and final volume confined by the tire
tread and rim (Vtire= 500mL). The compressor supplies air steadily
at 24°C and 190 psig. Assume air is an ideal gas, with CP=
(7/2)Rand R= 8.314 J/mol·K.Clearly state all assumptions.Final
answers should be appropriately rounded.
