Although Romano cheese is traditionally made in Italy from ewe's milk (Pecorino) the following recipe is prepared for a 2 gallon version of cows milk (which would technically be called Vacchino Romano).
Strength is usually tested by measuring permanent deformation of the container. Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Using this test helps maintain safety standards and durability of a vessel over time.
Hydrostatic Test Pressure Calculation Hydrostatic Test Pressure, P = 2St / D where, P S = Hydrostatic test pressure in psi = pipe wall. stress in psi. ASTM -50% of the specified minimum yield strength for austenitic alloy and stainless steel pipe JIS -60% of the specified minimum yield strength for austenitic alloy and stainless steel pipe. t D.
