14 deterministic calculators. Real formulas. Industrial context. Click a node to open the relevant category.
Preliminary calculation only. Not a certified engineering design.
Estimate flow velocity and flow characteristics from pipe diameter and flow rate.
v = Q / AEstimate required pipe diameter from flow and target velocity.
D from Q & vEstimate pipe friction loss using Hazen-Williams equation.
Hazen-WilliamsEstimate total dynamic head from static elevation, friction and fitting losses.
TDH = static + lossesEstimate hydraulic pump power from flow, head and efficiency.
P = ρgQH / ηEstimate volume for vertical, horizontal and rectangular industrial tanks.
V = πr²h or LWHEstimate steel pipe weight per metre and total for a length.
kg/m + totalFast conversions: bar↔psi, m³/h↔L/min, kW↔HP, °C↔°F and more.
14+ unitsEstimate chemical dosing requirements for water-treatment applications.
Dose rateEstimate filter loading rate from flow and filter area.
m³/m²/hEstimate chlorine contact time (CT) for water disinfection.
C × TEstimate hydraulic retention time from volume and flow.
τ = V / QEstimate wet abrasive blasting media consumption and time.
Coverage & timeEstimate spray coverage rate for tank cleaning nozzles.
m²/minEvery tool shows the formula, variables, worked example, limitations and direct links to the relevant ZAR capability.
Hazen-Williams, Darcy-Weisbach, pump affinity, CT, retention time — all shown transparently.
Examples drawn from actual water treatment, tank cleaning, piping and surface preparation work.
Every calculator links to the ZAR service that actually executes the work in the field.
ZAR Group delivers engineering, water treatment, tank cleaning, surface preparation and industrial equipment services across Malaysia. These tools are for preliminary thinking only — final design must be validated by a qualified professional.
