In my opinion and the way I practice, earthworms are directly (known weight of earthworms) are added to a tray containing known volume of luke warm water(37 to40C) and agitated for about 30 to 60Sec. The heat shock makes them to throw out the coelomic fluid through dorsal pores and the mouth in to tray. T he earthworms are collected back and added in to other tray containing water at room temperature. This helps them to overcome shock and the fluid sticking to their body mixes with the water. Earthworms will be safe and can be left back in to their bins. Mix the water in two trays and this will be the vermiwash or it is coelomic fluid in diluted form. As one is washing the earthworms in water, it is called vermiwash.
Coelomic fluid can be collected dirctly from the coelomic cavity by subjecting earthworms to cold shock or mild electric shocks. This is carried out to understand various components in coelomic fluid for scientific investigations.
Vermiwash can be used as spray in nurseries.
Coelomic fluid acts as a hydrostatic skeleton in some invertebrates, providing support for the body wall and aiding in movement. It also plays a role in nutrient transport, waste removal, and gas exchange within the coelom.

Coelomic fluid, in some organisms, acts like a hydrostatic skeleton. The pressure from the fluid aids in osmoregulation and circulation.
Mollusks use a structure called the crystalline style to extract useful molecules from their coelomic fluid. The crystalline style is a rod-like structure located in the stomach that grinds up food particles and releases digestive enzymes to break down food for absorption. This process allows mollusks to efficiently extract nutrients from their coelomic fluid.
coelom is a fluid filled cavity within the body between the epidermis and gut it is derived from mesoderm there are three types of coelomic cavity they are coelomemates psuedo coelomates and acoelomates
describe the differences between intravenous fluid and blood
Coelomic fluid is a transparent fluid found in the body cavity of certain invertebrates, serving as a hydrostatic skeleton. Hemolymph is a fluid found in insects and other arthropods that functions in nutrient transport and immunity. Blood is a specialized bodily fluid in vertebrates that carries oxygen, nutrients, hormones, and waste products, as well as playing a crucial role in immune response and temperature regulation. The key differences lie in their composition, functions, and the types of organisms in which they are found.
Phylum Cnidaria (e.g. jellyfish, corals) have an open circulatory system. This means that their circulatory fluid, called coelomic fluid, bathes their internal organs directly in nutrients and oxygen. There is no distinction between blood and interstitial fluid in an open circulatory system.
HAHAHAHAHAHA
The differential pressure equation used to calculate the pressure difference between two points in a fluid system is P gh, where P is the pressure difference, is the density of the fluid, g is the acceleration due to gravity, and h is the height difference between the two points.
The cytoplasm includes the cytoplasmic fluid and also some structures
There is no difference that I am aware of. These terms seem to be used interchangably.
