Buildings > Aqueduct Pump

Aqueduct Pump

Initial point for an aqueduct to begin. Used in the Test of Life.

To build:

Construction costs:

Built: in an aqueduct construction site by the Nile (actually in water)

Skill/Tech required: must be signed up for the Test of Life

Increase Size Costs

Pumps start at size 100. If you assume the size is actual size - 100, the following formulae work:

For people who don't do calculus, the easy way

First of all, these equations only work at size 100. Any other size, and you will get incorrect values.

Be sure to remember that actual size is actually the size minus 100!

To get accurate values, do f(x) - f(y), where x = size of the tower you are building to, and y = current tower size, and don't round until the final value. Due to rounding errors, your answer may be + or - one, especially on the fractional functions.

Functions:

Resource Equation
Bricks 200x + x^2
Concrete 10x + .05x^2
Cut Stone 3.7x + .013x^2

Gearboxes are required every time multiple of 5, and pipe segments are required every multiple of 10.

For people who do calculus, the faster, more accurate way

Just integrate the functions with bounds equal to the point that you start, and the point you end, with respect to x.

Your slopes, for ease of use:

Functions:

Resource Slope
Bricks 200 + 2x
Concrete 10 + .1x
Cut Stone 3.7 + .026x

Cistern Upgrades

Cisterns' capacity can now be increased via upgrading. Pumping the aqueduct reports the current maximum cistern capacity along with the current level. Here's what you need to upgrade:

To Reach Capacity Tar Leather Canvas Cable
200k 200 300 250 10
300k 400 600 500 20
400k 600 900 750 30
500k 800 1200 1000 40
600k 1000 1500 1250 50
700k 1200 1800 1500 60
800k 1400 2100 1750 70
900k 1600 2400 2000 80
1m 1800 2700 2250 90

Comments

Verified tile colors that match the requirements:

Each time you upgrade by 100 the next 100 costs extra bricks, concrete and cut stones e.g.

x = start height
y = final height
b = total bricks needed to upgrade
c = total concrete
cs = total cut stones

b = (x + y) * 100
c = (x + y) * 5
cs = ?

These are a work in progress and only hold for full 100 upgrades at the moment.

Gearboxes have remained at 20 per 100 upgrade and clay pipes have remained at 10.
