I know the inlet pressure, temperature and density along with the massflow rate across the orifice and the orifice cross section. Is there a way for me to calculate the drop in pressure across the orifice?

The flow rate through an orifice can be determined by using the Bernoulli's equation, which takes into account the pressure drop across the orifice, the density of the fluid, and the area of the orifice. The equation is Q = A√(2ΔP/ρ), where Q is the flow rate, A is the area of the orifice, ΔP is the pressure drop, and ρ is the density of the fluid.
The pressure drop across an orifice is affected by several factors, including the size and shape of the orifice, the viscosity of the fluid, and the velocity of the fluid. The pressure drop also increases with a decrease in the upstream pressure or an increase in the downstream pressure.
The pressure drop across an orifice can be calculated by using the Bernoulli's equation, which takes into account the velocity of the fluid, the density of the fluid, and the area of the orifice. The equation is ΔP = ρv^2/2, where ΔP is the pressure drop, ρ is the density of the fluid, and v is the velocity of the fluid.
The Reynolds number is a dimensionless number that is used to determine the type of flow (laminar or turbulent) in a fluid. It is important in calculating the pressure drop across an orifice because it affects the velocity and viscosity of the fluid, which in turn affects the pressure drop. For laminar flow, the pressure drop is directly proportional to the Reynolds number, while for turbulent flow, it is proportional to the square of the Reynolds number.
There are several methods for measuring the pressure drop across an orifice, including the use of pressure gauges, manometers, and flow meters. Pressure gauges and manometers measure the difference in pressure between the upstream and downstream sides of the orifice, while flow meters measure the flow rate through the orifice and use the Bernoulli's equation to calculate the pressure drop.
