Q:My faucet is loose, and I dont know how to tighten it...?
Loose where? If it is loose at the sink, where the whole faucet moves, you must tighten it from under the sink and you will most likely need a basin wrench. Go to the local hardware store and discuss this with the folks there. They should be able to give some better advice as I cannot ask questions. They will sell you the basin wrench and explain it's use as needed. Good luck!
Q:What are the models of faucet specifications? How to identify the faucet is good or bad?
Style, the current market is generally divided into two styles of faucet, that is, single handle and double handle faucet, single handle only a hole, and double handle can be divided into four inches and eight inch hole two, which can be based on Buy the basin style.
Q:A faucet is filling a hemispherical basin?
Equation of the hemispherical surface x² + y² + z² = R², (-R z 0) The volume of water in the basin with the height h: . . . (-R+h) V = ∫ π(x² + y²) dz . . . -R . . . (h-R) V = π ∫ (R² + z²) dz . . . -R V = πR²[(h - R) - (-R)] + (π/3)[(h - R)³ - (-R)³] V = πR²h + (π/3)(h³ - 3h²R + 3hR² - R³ + R³) V = πR²h + (π/3)(h³ - 3h²R + 3hR²) dV/dh = πR² + (π/3)(3h² - 6hR + 3R²) dV/dh = πR² + π(h² - 2Rh + R²) dV/dh = π(h² - 2Rh + 2R²) dV/dh = (dV/dt)/(dh/dt) dh/dt = (dV/dt)/(dV/dh) dh/dt = (dV/dt)/π(h² - 2Rh + 2R²) There is an ambiguity when you say HALF full. It can be interpreted as the water was filled up to half its maximum height (R) or filled up to half the volume of the basin (2πR³/3) I will take the case in which the water was filled up to half its maximum height: h = R/2 dh/dt = (dV/dt)/π(R²/4 - 2R*R/2 + 2R²) dh/dt = (dV/dt)/π(R²/4 - R² + 2R²) dh/dt = 4(dV/dt)/5πR² Plugging in dV/dt = 2000 cm³/min R = 30 cm dh/dt = 4*2000/4500π dh/dt = 16/9π cm/min. dh/dt ≈ 0.57 cm/min.
Q:What is the difference between a kitchen faucet and a straight drink faucet?
China has no direct drink of the first, because we are too much from the other, the foreign tap water is directly drinkable, their so-called direct drink is actually pure copper Faucet.
