Pump Calculations – New Flow Rate (Change in Impeller Diameter)‼️👇
📏 Metric Example:
Old Flow Rate = 184.56 l/min
Old Diameter = 200 mm
New Diameter = 0.285 × 200 = 57 l/min
✅ New Flow Rate = 52.6 l/s
📏 Imperial Example:
Old Flow Rate = 903.5 gpm
Old Diameter = 7.87 in
New Diameter = 7.26 in
✅ New Flow Rate = 833 gpm
🔍 Key Takeaway:
Changing the impeller diameter directly affects the flow rate. Use this formula for pump resizing or system optimization.

Cooling Tower Complete Calculations Package With Examples
Cooling Tower Design 101 All Calculations in One Place
Perfect for engineers working in pharma, chemical, HVAC, or utilities - here's your complete cheat sheet
1. Range
Formula: Range = Hot water temp - Cold water temp
Example: 42°C 32°C = 10°C
2. Approach
Formula: Approach = Cold water temp - Wet bulb temp
Example: 32°C - 29°C = 3°C
3. Cycle of Concentration (COC)
Formula: COC = TDS in circulating water / TDS in
makeup water
Example: 1800 ppm / 600 ppm = 3
4. Evaporation Loss
Formula: Evap = 0.00085 × Circulation Rate × Range
For 500 m³/hr and 10°C
Evap = 0.00085 x 500 x 10 = 4.25 m³/hr
5. Blowdown Loss
Formula: Blowdown = Evaporation / (COC - 1)
4.25/(3-1) = 2.125 m³/hr
9. Sump Volume (Water Level)
Formula: Sump = Retention Time (min) x Flow Rate ÷
60
5x50060 = 41.67 m³
10. Cooling Tower Capacity
Formula: Flow (m³/hr) = TR x 0.154
For 760 TR 760 x 0.154 = 117.04 m³/hr
Quick Summary Table
Parameter Formula / Value Example Value
Range: Hot temp - Cold temp 10°C
Approach: Cold - Wet bulb temp 3°C
COC: TDS ratio 3
Evaporation: 0.00085 × Flow × Range 4.25 m³/hr
Blowdown: Evap / (COC-1) 2.125 m³/hr
Drift Loss: 0.001 x Flow0.5 m³/hr
Side Stream Filter: 5% of Flow 25 m³/hr
Backwash: 3% of Side Stream0.75 m³/day
Sump Volume: (5 min x Flow) / 60 41.67 m³
Cooling Capacity: TR × 0.154 117.04 m³/hr.
Engineers, let's move beyond theory and apply these in real-world systems.
