## What are the 4 types of maintenance?

Four general types of maintenance philosophies can be identified, namely corrective, preventive, risk-based and condition-based maintenance..

## How do I calculate ppm?

Parts Per Million (ppm) Concentration CalculationsWrite an equation representing the ppm concentration: ppm = mass solute (mg) ÷ volume solution (L)Extract the data from the question: mass solute (NaCl) = 0.0045 g. … Convert the mass in grams to a mass in milligrams: mass NaCl = 0.0045 g = 0.0045 g × 1000 mg/g = 4.5 mg.More items…

## What is maintenance type?

Five types of maintenance are in fact recurrent in the industry: corrective, preventive, condition-based, predictive and predetermined. These concepts are not always easy to understand or are not well-known by certain people, that’s why they need to be cleared up.

## How do I identify tasks?

## What is ppm stand for?

parts per millionThis is an abbreviation for “parts per million” and it also can be expressed as milligrams per liter (mg/L). This measurement is the mass of a chemical or contaminate per unit volume of water. Seeing ppm or mg/L on a lab report means the same thing.

To task is to drain someone’s resources or to assign someone to do a particular job. An example of task is when a child took all his parent’s energy. An example of task is when you assign Joe the job of taking out the garbage.

## What are the tasks set for project planning?

The basic processes of project planning are: Scope planning – specifying the in-scope requirements for the project to facilitate creating the work breakdown structure. Preparation of the work breakdown structure – spelling out the breakdown of the project into tasks and sub-tasks.

## What is a good maintenance strategy?

An effective maintenance strategy is concerned with maximizing equipment uptime and facility performance while balancing the associated resources expended and ultimately the cost. We need to ensure that we are getting sufficient return on our investment.

## How much dissolved oxygen do fish need in ppm?

Fish growth and activity usually require 5-6 ppm of dissolved oxygen. Dissolved oxygen levels below 3 ppm are stressful to most aquatic organisms. Levels below 2 ppm will not support fish at all.

## What is a good PPM score?

A PPM defectives rate of 10,000 means the defect rate is less than 1%. However; with the passage of time, the expectations increased to 1,000 PPM and now, the expected PPM rate, especially in the manufacturing industry across the globe, is around 75 PPM.

## How do I make a 100 ppm solution?

1% water solutions: = 1g / 100g water = 1 / 100 = 0.01g / g water PPM Solutions 1 / 1,000,000 = 0.000001 = 1 ppm 1 gram of a 1% solution in 100 g water = 0.01g / 100g = 0.000100 = 100 ppm 0.1 gram of a 1% solution in 100 g water = 0.001g/100g = 0.000010 = 10 ppm To make a 1 ppm taste solution, add 10 grams of a 10 ppm …

## What is a task in a project?

A task is a single unit of work – an action to accomplish in a project, a single step in a multi-step project. … Just as project management is the coordination of individual tasks, a task can be broken down further into subtasks, which should also have clear start and end dates for completion.
