What is the difference between induced and forced draft cooling tower?

Induced draft --- A mechanical draft tower with a fan at the discharge (at the top) which pulls air up through the tower. The fan induces hot moist air out the discharge. This produces low entering and high exiting air velocities, reducing the possibility of recirculation in which discharged air flows back into the air intake. This fan/fin arrangement is also known as draw-through. (see Image 3)Forced draft --- A mechanical draft tower with a blower type fan at the intake. The fan forces air into the tower, creating high entering and low exiting air velocities. The low exiting velocity is much more susceptible to recirculation. With the fan on the air intake, the fan is more susceptible to complications due to freezing conditions. Another disadvantage is that a forced draft design typically requires more motor horsepower than an equivalent induced draft design. The benefit of the forced draft design is its ability to work with high static pressure. Such setups can be installed in more-confined spaces and even in some indoor situations. This fan/fill geometry is also known as blow-through.

What is the difference between machine and equipment?

Machines are devices that need a person's attention when operating. Equipment are devices that do not need this attention. Examples: a refrigerator is equipment, a steel cutter is machine, a stove is equipment, a computer or a fax are machines; we call it anyway, "fax machine". Your car is machine/you operate it; your house, though, is "equipped with A/C and fan" because you do not pay attention to them when operating. The water heater is equipment. The pressure washer is machine, the air-compressor is equipment.

The static pressure in my ductwork is 0.5 H2O supplied by a 500 cfm fan but I need an additional 1 H2O with no additional cfm will an additional fan with a 500 cfm rating work?

Okay, to get the static pressure in your duct to from 0.5" water gauge (w.g.) to 1.5"w.g., you could add another fan in series. Or, depending on your existing fan and motor size, you may be able to speed up your current fan to the pressure value desired. Additional airflow would be dampered down.

Which way should a fan spin?

It depends on how the fan blades are angled. If there angled right at 45 degrees then it should spin clockwise but if angled left 45 degrees anticlockwise. Please improve this answer since i am 11.
