How do you make a homemade salinometer?
How do you calibrate a homemade salinometer?
How does a simple salinometer work?
A salinometer generally works by passing an electric current through any known mass of water. Since salt water conducts electricity much more easily than pure water the salinity content of water can be easily calculated. … The chlorine ions help in conduction and hence these impurities increase conductivity of water.
How do you use a salinometer step by step?
Fill the container with water. Carefully insert the straw (clay covered end down) and add/remove clay until the straw floats at the maximum depth you wish. 3. Use the permanent marker to mark the depth where the salinometer floats in the water (0% salt solution).
What reading will the salinometer give?
salinometer, also called salinimeter or salimeter, device used to measure the salinity of a solution. It is frequently a hydrometer that is specially calibrated to read out the percentage of salt in a solution.
How can we make your own hydrometer?
How can you test the salinity of water yourself?
Use a thermometer to measure the temperature of the water sample. As long as you know the temperature of your sample, and the temperature standard of your hydrometer, you can calculate the salinity. For a slightly more accurate reading, you may heat or cool the sample to the temperature the hydrometer was built for.
How do you make a hydrometer with a straw and clay?
How many heat exchanger does a fresh water generator have?
The freshwater generator is based on two sets of shell and tube heat exchangers, one acting as evaporator or heater and other as condenser.
What is a fresh water generator What is its purpose onboard?
Fresh water generator, one of the important machinery on board a ship, is something that cannot be done without. Fresh water produced from fresh water generator is used for drinking, cooking, washing and even running other important machinery which use fresh water as a cooling medium.
What refers to the salt content of water?
Salinity (/səˈlɪnɪti/) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity).
How can I increase the production of my fresh water generator?
The capacity of fresh water generator can be varied by reducing or increasing the amount of jacket cooling water to the evaporator. The quantity of jacket cooling water to the evaporator can be adjusted by adjusting the bypass valve provided.
Why the correct vacuum is not achieved in fresh water generator?
Loss of Vacuum or Over-pressure of Shell
The shell pressure of the fresh water generator rises and rate of freshwater produced reduces. The reasons are: Air leaks into the evaporator shell in large quantities and air ejector cannot cope.
How are formation of scale on fresh water generator be minimized?
Excessive scales will lead to low quality of fresh water and also reduction in the quantity of water produced. It will also prevent higher reduction of pressure inside the chamber from taking place. Scale formation can be prevented by using a technique known as cold shocking.
What will happen to the drops of seawater removed by demister in the fresh water generator?
The water spray and droplets are partly removed from the vapour by the deflector mounted on top of the evaporator and partly by a build in demister. The separated water droplets fall back into the brine, which is extracted by the water ejector. … This is because the fresh water generator shell is at a lower pressure.
How do you keep a vacuum in a fresh water generator?
A vacuum of 85-95% is maintained in the system by a brine/air ejector. Seawater evaporates at a temperature of approximately 40°C due to the vacuum condition as it passes between the plates of evaporator heated by hot fresh water from the engine jacket cooling system, or by steam.
