Experiment: Water

The Water Experiment

The Water experiment is one of 12 experiments in the laboratory, available at laboratory tier 4.

The goal of the Water Experiment is to pump a certain amount of water and cool said water to a certain temperature.

Experiment

The water experiment consists of 2 main parts: the Tank and the Battery. The tank can initially hold up to 100 L of water.

Below the Tank are 3 buttons:

• Fill: Fills the tank at a rate of 1 L/s
• Freeze: Cools the contents of the tank down at a rate of 0.5°C/L/h
• Drain: Drains the tank at a rate of 1 L/s

Additionally, there is a button below the battery:

• Charge: Charges the battery at a rate of 2 W/s

You can only have 1 of these buttons active at any one time.

Upgrades

The upgrade store allows you to buy upgrades for the experiment tab. The price of each upgrade starts out at 100 , and gets multiplied by x100 every time you buy an upgrade. Prestiging (primarily the "Free Upgrade" prestige; "Lowered cost scaling" sucks even when spending upwards of e30 resources) is thus vital to being able to afford them. Upgrades and upgrade costs can be reset with the Reset button, along with all experiment progress; do this if you mess up.

Pump

The base rate at which water is pumped into or drained from the tank.
Rate: 2^lvl * 1L / sec., 4 upgrades.

Tank (Volume)

The maximum amount of water that fits into the tank.
Volume: 2^lvl * 100L, 8 upgrades.

Freezer

"The base rate at which the freezer cools down the water displayed in °C per L of water per hour." (It's actually °C times L of water per hour.)
Rate: 1.9^lvl * -0.5°C/L/h, 8 upgrades.

Overfill (Tank)

Allows the tank to be filled beyond the maximum at a slower rate. X represents the excess water.
Formula: None at lvl 0, otherwise 1/(1+X*(4.5-lvl/2)), 8 upgrades.

Battery (Max.)

The maximum amount of power the battery can store. (Should be in Joules, not Watts.)
Formula: 400W + lvl * 200W, 8 upgrades.

Power Usage

The battery consumption factor of draining, freezing and filling the tank.
Formula: .75^lvl * 100%, 8 upgrades.

Battery (Charge)

The base rate at which the battery charges up.
Formula: 2^lvl/2 * 2W / sec., 8 upgrades.

Overcharge (Battery)

Allows the battery to be filled beyond the maximum at a slower rate. X represents the excess power.
Formula: None at lvl 0, otherwise 1/(1+X*(4.5-lvl/2)), 8 upgrades.

Battery Boost (Pump)

Allows the battery to multiply the pumping speed. X represents the current power of the battery in W.
Formula: X^0.05*lvl, 8 upgrades.

Battery Boost (Freezer)

Allows the battery to multiply the freezing speed. X represents the current power of the battery in W.
Formula: X^0.05*lvl, 8 upgrades.

Time Boost (Freezer)

Increases the freezing speed based on the time spent in the current mode. X represents the time in seconds.
Formula: None at lvl 0, otherwise Log_10-lvl(X), 8 upgrades.

Time Boost (Battery)

Increases the charging speed of the battery based on the time spent in the current mode. X represents the time in seconds.
Formula: None at lvl 0, otherwise Log_10-lvl(X), 8 upgrades.

Prestige

Prestige drains all of the water from the tank, resets its temperature back to 20°C, the battery back to 0W, and changes the mode to idle (resetting any time bonuses accumulated). With the exotic skill, the water amount, temperature, and battery charge are all retained, and the mode is not switched (current time bonuses are retained). There are two prestige improvements to choose from:

• +1 Free Upgrade: You are able to buy an additional upgrade from the store for no charge.
• Lowered upgrade cost scaling: Lowers the cost scaling for store upgrades by 8% per level, as well as boosting the battery charge and freezer cooling rate by 3% per level (all bonuses are multiplicative). The price scaling multiplier is 100 * .92prestige per upgrade, while the charge/cooling rate boost is equal to 1.03^prestige. If you have the exotic skill, the cost scaling is applied retroactively.

It is recommended to purchase +1 free upgrade early on, then reset and transition to lowered upgrade cost scaling later on as it will easily outscale the +1 free upgrade.

Trivia

• The water experiment was reworked in update V0.8.4 B1
• The battery and the whole experiment displays power used as Watts per second (W/s), despite the Watt already being a unit of energy consumption (Joules per second).
• The module Absolute zero is a reference to the concept of Absolute Zero in physics.
