Sprinkler Hydraulic Calculator

Sprinkler hydraulic calculation service converts the water demand and critical circuit conditions of the defined design scenario into a calculation report. MKA Engineering carries out the calculations of new projects and control of existing projects according to its service scope. General system selection and scope of application are described on the separate sprinkler service page.

Technical Approach

The basis of hydraulic calculation is the correct design criterion.

Hazard class, design area, application density and system geometry of the spaces to be protected are decisive in sprinkler calculation. The pump requirement is evaluated by taking into account pipe diameters, simultaneously operating sprinklers and critical circuit pressure losses.

01

Hazard Class

The necessary information is examined to determine the design principles according to the use of the location and storage conditions.

02

Hydraulic Critical Circuit

Sprinkler placement, elevation differences, line lengths and local losses are transferred to the calculation model.

03

Flow, Pressure and Pump

The flow-pressure point required by the system is compared with the existing or proposed pump characteristics.

04

Project and Revision

Line diameters, installation layout and revision suggestions, if necessary, in accordance with the calculation results are included in the project.

Working Method

From discovery to project, from project to field.

The scope of work is determined by the size of the project and existing system data.

01

Risk and location data

Purpose of use, storage method, locations and plans are examined.

02

Sprinkler placement

The design area and line layout are determined.

03

Account verification

Critical circuit, losses, level difference and pump point are checked.

04

Reporting

Calculation printouts and application coordination notes are prepared.

Offer and Preliminary Evaluation

Information needed to get started

For preliminary technical evaluation, the following data available may be shared:

  • Architectural plan, space usage and ceiling information
  • Shelf height and product class if storage
  • Existing or planned pipe routes
  • Flow-pressure data of pump and water source
Standard and Application

Project criteria

According to the project conditions, the relevant design criteria within the scope of BYKHY and TS EN 12845 are evaluated; Situations requiring different references are determined separately.

Each project is evaluated separately according to its own structure and usage conditions.

Frequently asked questions

How to prepare a quote for Sprinkler Hydraulic Calculation?

Design criteria, usage and storage data are shared along with the facility's district, usage type and desired service. Account, project, application and test items are separated in the written scope.

Will existing drawings be sufficient?

The drawings are compared with the field. If there are revisions, changes in use, and missing equipment information, their impact on the account or project is examined.

What documents are submitted?

Calculation acceptances and the method used, critical circuit and node results and other documents included in the scope of work are delivered. The file format and revision scope are determined at the outset.

Is fixed capacity used for each facility?

No. Usage, system structure and field data are different. Numerical values ​​cannot be applied to all facilities without verifying the relevant calculation and method.

Are implementation and control the same scope?

Project planning, assembly, field inspection and testing tasks are defined separately. The proposal states which party is responsible for which work.

From which regions do you receive requests for exploration?

Requests from Çorlu, Ergene, Kapaklı and Tekirdağ are evaluated from our Çerkezköy center. The time and conditions of the field visit are decided separately.

Discovery and technical proposal request

Share the facility location, current project status and the service you want for the Sprinkler Hydraulic Account. Let's clarify the scope of discovery, calculation, application and delivery together.

Related service and region information

The water demand determined in the hydraulic calculation depends on the pump selection. fire water tank and supply infrastructure also requires evaluation. Tank and pump components are considered together based on the facility's validated design inputs.
