Water

At 100% clock speed, one Coal Generator consumes 45 m3 Water/min, no matter what fuel is used.

Ratio's

Number of Coal Generators required (100%):
Coal generator = Coal mining rate / 15

Number of Water Extractors required:
Water extractor = Coal generator / 2.6666

Spread out the water supply across multiple Mk.1 pipelines as following:
Mk.1 Pipelines required = Coal generator / 6.6666

Some commonly used ratios are:

Miner Mk.	Purity	Coal/min	Water Extractors (@ 100%)	Water Extractors (@ 75%)	Water (m³/min)	No. of Coal Generators	Gross Power
Mk.1	Impure	30	0.75	1	90	2	150 MW
	Normal	60	1.5	2	180	4	300 MW
	Pure	120	3	4	360	8	600 MW
Mk.2	Impure	60	1.5	2	180	4	300 MW
	Normal	120	3	4	360	8	600 MW
	Pure	240	6	8	720	16	1200 MW
Mk.3	Impure	120	3	4	360	8	600 MW
	Normal	240	6	8	720	16	1200 MW
	Pure	480	12	16	1440	32	2400 MW
