Spherical tanks distribute the vapor pressure from within the tank equally to the inner surface of the tank.
If one were to make a tank a cube or a cylinder, you would have to use a lot more metal to create a tank strong enough to hold the same amount of boiling liquid.
Dams are built in a curved manner (check images of the Hoover Dam) along the same principles- to distribute pressure evenly to a curved surface- rather than making it straight.

What is Siwoloboff method - slide6?
Siwoloboff's method is a method used to establish the boiling point-composition curve of a binary system. It is particularly well adopted for the determination of boiling points of small samples of pure liquids and of mixtures. In this method, the open end of a short capillary tube (sealed at the other end) is immersed in the liquid under investigation. The tube serves as a manometer to determine the temperature at which the vapor pressure ofthe liquid is equal to the pressure of the atmosphere (boiling point definition)
How do you maintain net positive suction head of a pump?
first of all the term NPSH should be clear.It is pressure which should be available at the eye of the pump impeller,so as to avoid vaporisation of liquid. Second which arises ,how this liquid will vaporise?Ans-if a vapour pressure of a liquid falls at constt temperature or temperature of liquid is raised at constt pressure it vaporises.In case of pump it's mostly the first case. Now,how to manitain NPSH. NPSHa> NPSHr (always) where NPSHa= available NPSH NPSHr = Required NPSH NPSH = Hps+Hsl-Hvp-Hfl Hps= pressure acting on the eye due to pressure in the suction drum. Hsl = pressure acting due to height of liquid in the suction line. Hvp= vapour pressure of the liquid Hfl= head loss due to friction losses Thus, to maintain the NPSH, variables in hand are,Hps and Hsl.increase the height of the suction line or increase the pressure of the suction drum.
What is steam in thermodynamics?
Saturated steam is gas-phase water in equilibrium with liquid water at the same temperature and pressure. If the temperature is above the saturation point and/or the pressure is below the saturation pressure, the steam is "superheated steam". In either case it is a gas. There are some conventions where saturated steam along with some fraction of liquid water in equilibrium with it is still referred to as steam even if not all of it is gas, as long as at least some of it is gas.
What state of matter can be used in hydraulic systems?
State? Or phase? It would be a liquid phase. But its state is unknown since the state of a substance includes its pressure, temperature AND phase. Phase is a part of a state, but a state is not a phase.
Why there are boiling range not boiling point?
I am not sure but may be it is because none of the substances have a fixed boiling point. The substance starts changing its state from liquid to gas before the mentioned boiling point . For example Boiling point of H2O is 100.but it change it changes its state before it.Therefore there are boiling range not boiling point.
What is the saturation temperature of vapour or the boiling temperature of a liquid?
The saturation temperature of a vapor is the temperature at which it condenses to a liquid at a given pressure. It is also known as the boiling temperature of a liquid, as it is the temperature at which the vapor pressure of the liquid equals the surrounding pressure, resulting in boiling.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is?
The temperature at which the vapor pressure of a liquid equals the external pressure is called the boiling point. This is when the liquid changes into vapor at a constant temperature.
When atmospheric pressure increases what happpens to the boiling temperature of a liquid?
The boiling temperature of a liquid increases as the gas pressure a the liquid's surface increases.
What happens at a liquid's boiling point?
Boiling. A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it.
What is the temperature where the vapor pressure of a liquid equals atmospheric pressure?
The boiling point of the liquid.
What is the point at which a liquids vapor pressure equals the atmospheric pressure?
The boiling point of a liquid is the temperature at which its vapor pressure equals the atmospheric pressure. At this point, bubbles of vapor form within the liquid, leading to a phase change from liquid to gas.
What term defines the temperature at which the vapor pressure of the liquid equals the atmospheric pressure?
The term is "boiling point." At this temperature, liquid changes to vapor as its vapor pressure is equal to the atmospheric pressure.
What can be said of a boiling point of a liquid?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to change into a gas. It is a characteristic property of the liquid and can be influenced by factors such as pressure and impurities in the liquid.
As external pressure such as atmospheric pressure on liquid increases its boiling temperature?
At high pressure the boiling point is higher.
What is the name for the temperature when liquid turns into a gas?
It's called the boiling point. It is the temp where the vapor pressure of the "liquid" is equal to the air pressure around (above) it. This is when the liquid [water] reaches 100 degrees Cecilius [at sea level].
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?
The temperature at which the vapor pressure of a liquid is equal to the external pressure is known as the boiling point. At this point, the liquid changes to a gas by overcoming the external pressure.
What can a boil be defined as?
Boiling, a type of phase transition, is the rapid vaporization of a liquid, which typically occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure.
