This post is continuation of my first post about my participation in workshop on microhydro power plant in national seminar on instrumentation, control, and automation. Please read the first post first to get overall picture of the workshop.
I am lucky to see some of main equipments in microhydro power plant workshop. Picture below is example of microhydro power plant for study purpose. Read More
On 11-12 December 2018, I had an opportunity to participate in national seminar on instrumentation, control, and automation, as well as microhydro workshop. This event was held by CITA ITB (Center for Instrumentation Technology and Automation Institut Teknologi Bandung, Indonesia). It was a really awesome event, especially workshop on microhydro. In this post, I want to share to you what I got from the workshop. Read More
In this post I want to share to you how to do preliminary sizing and horse power estimation for counterflow induced-draft cooling tower. Calculation in this post do not apply to counterflow cooling tower. Also they do not apply when the approach to cold water temperature is less than 5oF (2.8oC). Read More
In this post, I want to share to you how to size cooling pond. Cooling pond is used to remove heat from water by means of air. Example of application of cooling pond is to remove heat from brine water in geothermal power plant facilities.
To design cooling pond, you need process data and environment data. Process data are flow rate of liquid to be cooled, initial temperature, final temperature, and density of liquid. Environent data are relative humidity, wind velocity, average air temperature, and solar heat gain. Here is example of cooling pond sizing. Read More
Based on RUPTL PLN 2018, installed capacity of solar power plants in Indonesia is only 78.5 MW. It is the lowest capacity among other type of renewable energy sources. I wonder what makes this happened.
