Hemispherical head is the strongest of all heads.Therefore it is used.
The ASME Boiler and Pressure Vessel Code details all the various calculations necessary to determine the MAWP of any pressure vessel.
I guess it depends on whether it's sealed or not. If it's open to the atmosphere how can it be under pressure ? If it's sealed it could be put under (positive or negative) pressure so would be, by definition, a pressure vessel IMHO.
An ASME "U" stamp designates a vessel as a "pressure vessel" as defined and regulated by ASME codes
Pumps consist basically of pressure vessels and equipments for supplying compressed air.Concrete is delivered in to the pressure vessel and the vessel sealed tightly.Compressed air is then supplied to the top of the vessel which pushes the concrete out through a pipe connected at the bottom.
there is not enough information. 4 cubic meter of air at 24degC does not define how much air there is, as we don't know the pressure. One thing we do know is that the pressure will double as you are cutting the volume in half (Boyle's law)

A 'ballpeen ' hammer is an engineering hammer with one flat head and one hemispherical head.
it just means that the head on the motor is hemispherical. That means it has a curve to it.
Certified Pressure Vessel
The answer depends on the pressure vessel.
When a sailing vessel and a pwc are meeting head on the sailing vessel is the stand on vessel.
hemispherical
When water freezes in an enclosed vessel, it expands and exerts pressure on the vessel walls. This pressure depends on factors such as the volume of water, rate of freezing, and strength of the vessel. Generally, this can lead to the vessel cracking or bursting if the pressure becomes too high.
A vessel implodes when the pressure inside the vessel becomes greater than the pressure outside, causing it to collapse inward. Factors that contribute to this phenomenon include a sudden change in pressure, structural weaknesses in the vessel, and the material properties of the vessel.
To calculate the weight of an empty pressure vessel, you can determine the volume of the vessel and then multiply it by the density of the material from which the vessel is made. This will give you the mass of the vessel, which you can then convert to weight by multiplying it by the acceleration due to gravity.
The main purpose of a pressure vessel is to hold gases or liquids at a pressure inside a container different to the pressure outside of the pressure vessel. Usually pressure vessels are made from steel.
