How to calculate spanner size regarding bolts and nuts
Yes.
refer to TROX
Count up the number of obseravtions made on the experimental units. That is the sample size.
You cannot "calculate" the front of a box. You can calculate its dmensions, or its area but calculating it does not make sense. As for calculating its size or area, the answer will depend on what information you have and what you require.

Faster river velocities are capable of carrying greater amounts of bedload and transporting them farther and faster. The shape of the sediments of the bedload would therefore be exposed to more physical weathering which would progressively round the sediments and also decrease their size.
waste transported from the river!
a bedload
bedload
River efficiency is how easily a river can move water, sediment and bedload.
How to calculate spanner size regarding bolts and nuts
M. A. Carson has written: 'Bedload transport in gravel channels'
The size of the pebble will decrease down stream because the further downstream you go the quicker the river velocity. This means there will be more abrasion against the sides and bed of the river and the friction will be greater, this wears away the river load making it decrease in size. Increase velocity means that bigger material will be picked up by the river and carried as river load. More load in the river and increased size of load will mean more attrition and the river load will keep colliding into each other smoothening and rounding their shape. Brap brap !!
Answering "How do you calculate the size of a dry well for a house?"
It is sediment transported by a river that becomes too heavy to be in suspension and thus sinks
The bedload becomes smaller when the river is flowing downstream, and the rocks also become smaller, smoother and rounder due to attrition and abrasion. (The reason the flow slows down is because the energy of the flow decreases.)
