🔧 Cavitation in Pumps –‼️👇🏻
Cavitation happens when the pressure in the suction line drops below the vapor pressure of the liquid, forming bubbles. These bubbles collapse inside the pump, causing damage to the impeller, noise, and reduced efficiency.

⚠️ Avoid Cavitation By:
Maintaining proper suction pressure

Using correct pump speed and NPSH

Designing proper suction piping

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.

Valve Components Breakdown 🛠️🔧
Here’s a detailed explanation of the labeled parts of an industrial valve, along with their functions and relevant hashtags:
1. Top-Mounted Handwheel
Function: Manual control for opening/closing the valve.
Common in: Gate valves, globe valves.
#HandwheelControl #ManualValve #IndustrialHardware
2. Actuator (Automated Models)
Function: Automates valve operation (electric/pneumatic/hydraulic).
Replaces: Handwheel in automated systems.
#ValveActuator #Automation #SmartValves
3. Stem
Function: Connects handwheel/actuator to the plug/disc.
Critical for: Transmitting motion to seal/unseal flow.
#ValveStem #MechanicalSeal #FlowControl
4. Yoke & Coupling
Yoke: Supports the stem and actuator.
Coupling: Links actuator to valve body.
#StructuralSupport #ValveAssembly
5. Packing Set
Function: Prevents leaks around the stem.
Materials: Graphite, PTFE, or fibrous compounds.
#LeakPrevention #SealingTech #MaintenanceMatters
6. Cage (in Control Valves)
Function: Guides the plug and modulates flow.
Key for: Pressure/temperature regulation.
#ControlValve #FlowModulation #ProcessEngineering
7. Plug/Disc
Function: Seats against the valve body to stop flow.
Designs: Globe (plug), gate (wedge), or ball valves.
#ShutOffMechanism #ValveCore #FluidDynamics
8. Body
Function: Main pressure-containing component.
Materials: Cast iron, stainless steel, brass.
