Your hot water heater may not be working, or the pipes are cold enough to cool down the water by the time it reaches you. As the pipes heat up you’ll get hot water.

If we fall into a sea of liquid, how hot does it need to be for us to die instantly and painlessly?
Instantly is a matter of opinion, so let’s focus on painless. Temperature is tricky as you will have some build up prior to the point of execution, also orientation and speed on emersion can become significate. So let’s layout the most likely scenarios. Destruction of the body faster than nerves can fire and be processed …
Is the Earth in imminent danger of a crustal displacement?
Yes. But since it rarely gets as high as a 1/4″ per year it tends to be a small concern.
When people say “2 blocks away,” how far is that?
Two intersections away, two lighted intersections away, or about 200′-500′ away.
Is sand that we read in building material different than that we read in soil mechanics?
Sand as a building material is virtually any granular material. In soil mechanics, it is mineral-based material 0.074mm – 4.75mm in size. So, the soil mechanics definition is more precise than the building material definition.
What building materials (e.g. marble) were used to make Amiens Cathedral?
The principal material used in its construction was stone. While documents agree that the stone was quarried locally I’ve never seen anything that was able to identify the type of stone. If you’re not familiar with stone construction it is very similar to brick masonry construction. The stone is shaped and put in place with …

Why is the water flow more rapid out of a faucet on the first floor of a building than in an apartment on a higher floor?
Unless there is a water tank or booster pump you are going to loose about 0.4 psi per foot vertical. Given that most floors are about 10ft floor-to-floor that is 4 psi loss. So, if a first floor unit has 30 psi water pressure, the fourth floor unit has about 12 psi water pressure if …
Are architects interested in making floating buildings through levitation?
Yes, though it might depend on the definition you’re using for levitation. We float a structure on a liquid like a boat, but I don’t think this is what you mean. Or in a gas like a balloon, but again this requires huge gas bags for buoyancy which will quickly limit your weight. Magnets and …

What are the primary causes for the wind on Earth?
Short answer; temperature. Air is largely affected by temperature, which causes hotter air to rise above colder air. The sun is always heating a portion of the Earth, but not others, creating a hot spot which change the air temperature. Next major item is humidity or moisture content. the more water vapor present the heavier …

What is the best way to divert rain water or snow melt from running off the roof above a doorway?
First, let’s assume you can’t change your roof in any significant way. You are looking for an element called a rain diverter. Basically, this is an ‘L’ shaped piece of flashing attached under the trailer edge of your roof tiles/shakes/slats. In most cases it only needs to be 1.5″ to 2″ high to catch the …
