Calculation to Determine Internal Diameter of Pipe for a Pumping System

In order to determine internal diameter (ID) of pipe for a pumping system, there are 2 parameters that we need to know which are flow in the pipe (Q), and its velocity (V). The formula is as shown in the picture below. Q is the required flow for the system that we design, while V […]

Calculation To Determine Engine Power For Hydraulic Submersible Pump

Firstly, we need to understand the distribution of power to transfer some amount of water (Flow) to the specified height (Total Head). The distribution of power for the hydraulic submersible pump is as follow: In order to determine the Engine power, we need to calculate the Brake Power at Hydraulic Pump Shaft in Hydraulic System. […]

Operasi dan Penyenggaraan Kapal Korek Jenis Cutter Suction Dredger

Prinsip asas operasi kapal korek jenis cutter suction dredger dibahagikan kepada tiga (3) bahagian, sebagaimana berikut: Bahagian pertama ialah pasir atau tanah berpasir di dalam air akan digali menggunakan mata pemotong (cutter drive) yang akan bergerak secara menegak (untuk mendalamkan penggalian) dan melintang (untuk meluaskan kawasan penggalian). Kedua-dua arah pergerakan ini, masing-masing digerakkan oleh cutter ladder […]
