Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Question

3- State which of the following statements are TRUE?
a) For a backward curved blade, the fan total pressure (FTP) increases as
flow
rate increases
b) For a backward curved blade, the fan total pressure (FTP) reaches a
maximum at a particular flow rate
c) When the air filter in the air conditioning duct becomes dirty, the speed
has to
be increased to maintain the balance between fan and duct systems
d) When the damper installed in the duct is opened more, to maintain the
balance, the speed of the fan should be increased

The following air streams mix in a building’s HVAC system upstream of the HVAC heating unit: 1,600 CFM outdoor air at 35°F and 70% RH mixes with 3,500 CFM of return air at 70°F and 40% RH. Assume the HVAC runs for 1 minute, so CFM is the same as cubic feet. a) What are the temperature and RH of the combined air stream? b) How much energy (units of BTU) does the HVAC heating unit need to add to the combined air stream to condition it to 80°F and 60% RH? c) If the conditioned air stream from the heating unit then mixes with 28,000 CFM of air at 70°F and 40% RH provided to the building from another source, what are the combined temperature and RH of the air in the building?
