The bachelorâs degree in engineering is a challenging program that requires a substantial amount of coursework in mathematics and natural sciences in addition to the core and elective engineering classes.
Fire Sprinkler Head - Minimum Pressure Requirement. I am reviewing Hydraulic Calculations for a wet type fire sprinkler system to be installed in an existing building. The new sprinkler system will connect to an existing fire pump fed by a 25,000 gallon underground water storage tank (the tank is dedicated to fire protection). From the hydraulic calculations, it appears that the designer is using a minimum pressure of 14 psig at the sprinkler heads located in the Hydraulic remote zone.
6.0 Condenser Water Temperature Control: For installations where entering condenser water temperature could be lower than 65Â°F Multistack recommends the installation of a three-way tower bypass valve to maintain a minimum of 65Â°F entering condenser water temperature. This is based on a 10Â°F delta-T system. 7.0 Pressure Relief Piping and Refrigerant Monitoring: Multistack modules utilize a small charge of refrigerant (typically .6 lbs per ton) so are often exempt from ASHRAE 15 Standard.
