Calculation of emissions

There is a discharge pipeline (leading to a constant-pressure storage tank). When the inlet pressure is 0.6 MPa, the discharge rate is 0.03 m³/minute. What is the discharge rate when the pressure rises to 1.5 MPa? How is it calculated?
According to Bernoulli’s equation, the flow rate formula can be expressed as Q² = (CdAρ)², where Q₀ is the mass flow rate of the liquid leaking, in kg/s； Cd — Liquid leakage coefficient, selected according to Table 5.3-1 ； A —— crack area, m2 ； ρ —— Density of the leaking liquid, kg/m3 ； p1 —— Pressure of the medium inside the container, Pa ； p2 —— Environmental pressure, Pa ； g —— acceleration due to gravity, 9.8 m/s2 ； h —— liquid level height above the crack, h1-h2, m.
I would be very grateful if you could tell me the source of the formula on the 2nd floor and its applicable conditions! ! ! !
