Determine MUA distribution to maintain pressure in space

[Thao Hoang]

hi,
i have a little side project that I'm currently stuck on.
there are three separate space/zone that is being supply by 10000 CFM of outside air. the min. requirement for each zone are: zone 1 need 2500 cfm, zone 2 need 1100 cfm, and zone 3 need 1300 cfm. A) determine the make up air distribution is needed to maintain pressure in each space. B) generate a pressurization map.
i know that i need to apply the bernoulli's to solve this problem but don't know where to start. any guidance is appreciated.

To solve this problem, you can start by using the Bernoulli's equation to calculate the pressure that is needed in each zone to ensure that the required CFM of outside air is supplied. For example, for Zone 1, you would need to calculate the pressure difference between the total outside air supply (10000 CFM) and the required flow rate of Zone 1 (2500 CFM). Once you have the pressure difference for each zone, you can then use this information to generate a pressurization map. This map should show how the pressure drops or increases as air moves from one zone to another.
