On which property of water, will the accumulator in Water jet machinin

1.	On which property of water, will the accumulator in Water jet machining rely on?(a) Density(b) Compressibility(c) Viscosity(d) VelocityThis question was addressed to me during an interview.The above asked question is from Water Jet Machining topic in portion Mechanical Processes of Advanced Machining
Answer» RIGHT answer is (b) Compressibility To explain I WOULD say: Accumulator relies on compressibility of WATER (12% at 3800bar), in order to maintain a uniform discharge PRESSURE in WJM.
