Tank and liquid consuming apparatus including the same

A tank configured to be installed in a liquid consuming apparatus having a liquid consuming unit and be connected to the liquid consuming unit such that liquid flows between the tank and the liquid consuming unit, the tank comprising:

• a casing having a bottom wall, a rear wall, and a side wall in a usable posture of the tank, the side wall extending in a direction intersecting with the bottom wall, the rear wall extending in a direction intersecting the bottom wall and the side wall;
• a storage chamber provided in the casing and configured to store the liquid;
• and
• a communication port provided in the storage chamber to let the liquid flow out to an outside of the tank from an opening through the rear wall,
• wherein the storage chamber includes:
• a first space extending along the bottom wall from the communication port;
• and
• a second space connected to the first space in a vicinity of the communication port and extending along the side wall and the rear wall from the communication port, and
• in a state that the liquid is stored at least in the first space and the second space, a first pressure loss when the liquid stored in the storage chamber flows to the communication port via the first space is equal to a second pressure loss when the liquid stored in the storage chamber flows to the communication port along the second space.
