## How do you calculate grams per liter concentration?

Methods of Calculating Solution Concentration

1. Grams per liter represent the mass of solute divided by the volume of solution, in liters.
2. Molarity describes the concentration of a solution in moles of solute divided by liters of solution.

## How do you calculate salt concentration?

First, we must convert the mass of NaCl in grams into moles. We do this by dividing by the molecular weight of NaCl (58.4 g/mole). Then, we divide the number of moles by the total solution volume to get concentration. The NaCl solution is a 0.1 M solution.

## Why is batch culture used?

Fed-batch culture has been used in two major ways by the fermentation industry: To control the oxygen uptake rate of the process organism such that its oxygen demand does not exceed the oxygen supply capacity of the fermenter. To control the specific growth rate at an optimum value for product formation.

## What are the advantages of continuous production?

• Reduced Labour cost,
• High accuracy,
• Reduced material handling,
• Simple control process,
• Minimum wastage,
• Better materials /inventory control,
• Higher return on investments.

## What are the features of continuous production?

Process, materials, machines and an uninterrupted flow of materials are the key characteristics of continuous manufacturing. In process production, the demand for the product is continuous and high. The materials can create different products at different stages of manufacturing.

Process control

## What is the difference between mass and continuous production?

Mass production – A large number of the product is made on a production line. This is often called repetitive flow production. Continuous production – Many thousands of the product are made. The difference between this and mass manufacturing is that continuous production is on 24 hours a day.

## What is one off production example?

One off production is the manufacture of a single product/item. This can include large scale projects, such as a bridge, ship, stadium, multi- storey building or tower, Other examples of one offs are – specialist jewellery, made to measure clothing, bespoke furniture and many more.

## What are the 4 main scales of production?

There are four terms used to describe the scale of production in relation to manufacturing a product:

• prototype and one-off production.
• batch production.
• mass production.
• continuous production.

## What is high volume production?

High-volume manufacturing is the same as mass production: fabricating large quantities of goods in short periods of time. Goods that are produced in high volume often have little or no variation. High-volume manufacturing processes are the types of processes that manufacturers use to mass produce goods.

## What are the four Vs?

All operations processes have one thing in common, they all take their ‘inputs’ like, raw materials, knowledge, capital, equipment and time and transform them into outputs (goods and services). They do this in different ways, and the main four are known as the Four V’s, Volume, Variety, Variation and Visibility.

## What is high mix low volume manufacturing?

In the EMS industry, the term high-mix, low-volume (HMLV) refers to CMs or OEMs who change over production between assemblies and processes much more often than their low-mix, high-volume (LMHV) counterparts.

## What is production volume?

Production volume measures the total amount your company can produce over time. This KPI tracks the total number of products manufactured over a set period of time (days, weeks, months, quarters, years) and focuses on total output.
