Development of a watermist cooling system: A 12,500 Kcal

Waterspray aircooled water chillers that are currently available on the market mainly depend on water mist to cool the system this tends to rust base frames and accumulate water around the unit. This study was intended to maintain the performance of the waterspray type aircooled water chiller while mitigating its shortcomings.

Calculation of Water Spray for Fire Protection of Vertical

I just got an assignment from my boss to calculate fire protection of vertical vessel. NFPA 15 (National Fire Protection Association 15) is a standard for water spray fixed system for fire protection.
