1. Use of Bernoulli principle: A CRAH unit delivers 9000 cfm in a semicircular path under a 0.5 ft raised floor. The area of the exhaust opening from the CRAH is 8 ft x 2 ft. Estimate the pressure at a radius of 8 ft and 20 ft from the CRAH unit. Assume incompressible flow and assume all the energy at the CRAH exhaust is kinetic energy. Which direction is the air flow through the perf tiles located at 8 ft and 20 ft.? CRAH (2 x 8 ft) r=8ft 20 ft. 1.
