Booster pump calculate :
Calculate find size of pump for make booster pump
1 tap water flow = 10 liters per minute
So : 10 x amount of room = usage water per liter per minute
Exp : If have 40 rooms will use cold water ?
Ans : = 400 Liter per minute
Exp : If have 40 rooms usage cold water and hot water . peak load will be?
Ans : = 800 Liter per minute
When we know the amount of cold – hot water already we will find the size pump.
Notice : we must thinking of pressure drop of equipment and all curve of pipe be 0.5 bar – … bar up to equipment
Notice : we must fix the working of percentage exp : 30% working , 60% , 80% to know the amount of runing pump
Exp : If we use cold and hot water per 40 rooms how much size pump we will setting.
Ans : 40 x 10 CW , 40 x 10 HW = 800 Liter per minute
If we use pump : 110 -280 Liter per minut , Q = 30-35.5 M. all 3 units if run pump 30% = 240 Liters per minute run time of pump is 1 unit
If we run pump 60% = 480 Liters per minute run time of pump is 2 units and 80% = 640 Liters per minute run time pump is 3 units
So we must find the size of pump for usage : and cover for pressure drop.
