1/Most people fail to realise that ‘a litre’ is a measure of volume. Because most liquids are measured by volume,a large majority of otherwise apparently sentient people choose to think it applies to liquids and ONLY liquids. Not so-a litre is a measurement of volume,regardless of the chemical composition or solidity of materials relating to that volumetric measurement.
2/The main reason for compost to be sold by volume rather than weight is that the moisture content will have a significant effect on the weight,but to a lesser extent affect the volume. It lets you know how many pots of a given volume you can fill,rather than how heavy they’re going to be.
Oh-and the GROSS weight of a ship will include NOT just the ship = cargo tonnage…but will include the weights of the crew,fuel,supplies,tools and incidental equipment or items that may be along for a one-off ride,or may be personal items belonging to crew-members. ALL these ‘external’ considerations MUST be included in the GROSS weight assignable to any vessel. DISPLACEMENT-as some insist ‘gross weight’ refers to,is a completely different field-and equasion-as it relies NOT JUST on the full amount of displaced water being uniform in density and salinity,but also in density AND toxicity…as both of these have an effect on the amount of water a 1,000-ton ship will displace. For instance;approaching Hong Kong harbour,a 24,000-ton vessel will be displacing circa 2,000 tons more water-ie; riding lower in the sea,than the same vessel at the same weight,entering the Gulf of Mexico…which is filled with circulating toxins,salinity erupting from it’s bed,an ‘oil density’ factor due to drilling - so,that same vessel at the same weight and speed,with be circa 4’ lower in the water as it enters the Gulf…“Cargo=400 tons…right,close the hatches” doesn’t cut it. The GROSS allowable weight of a vessel in saline water,allowing a full 2-metre clearance between the hull and the sea-bottom [because waves can be unpredictable] is ALWAYS less than the hull has been designed to be safe at…usually 25 tons less. PLUS,differences in water cleanliness,density,oil-factors…and even the temperature of the water per-se,all combine to ensure that any ‘given’ weight-and-displacement of a vessel has it’s variants,according to clime,temperature,salinity and cleanliness of the water.
Oh…[sorry,nearly forgot]…and the volume of a sphere is simple and very basic mathematics,bro. Just,in effect,Pi x r to the required formulaic.
so,[scuze me,all you bored peeps];
Vsphere if r = 2 inches
Vsphere = 4/3 × pi × r3
Vsphere = 4/3 × 3.14 × 23
Vsphere = 4/3 × 3.14 × 8
Vsphere = 4/3 × 25.12
Vsphere = 4/3 × 25.12/1
Vsphere = (4 × 25.12)/(3 × 1)
Vsphere = (100.48)/3
Vsphere = 33.49 inches3 …so all you’ve done really,is equate pi to a simple formula…i.e; V = (4/3) × pi × r3…[or/plus, you can use pi = 3.14]
So,now to answer the incoming flak -
1/no,I don’t use that fkn Google thing. Sod Google…
2/Yes,both my braincells work-though not often in sync.
3/I have no idea how I hold 3 degrees in wildly differing fields,as all I’ve ever been is curious,NOT wildly,‘John Nash’ style intelligent.Put it down to karma.
4/Fuktiffino!
Right…as you were,gentlemen…and that noo bird,natch…
