testdata_MB: List of functions and constants for test (and example)

In sshunsuke/MukherjeeBrill: Mukherjee & Brill model for gas-liquid two-phase flow in a circular pipe

Description

A list containing functions and constants for fluid properties used in tests (see also Value). SI unit is used.

• Mair: Molar mass of air - kg/mol

• Sutherland_vis0_air: Viscosity of air at 273 K - Pa-s

• Sutherland_T0_air - K

• Sutherland_C_air - K

• ideal_gas_density(temperature, pressure, M) - kg/m3 (K, Pa)

• Sutherland_viscosityG(temperature, viscosity0, t0, const) - Pa-s (K, Pa-s, K, K)

• Kerosene_surfaceTension(temperature): K

• Kerosene_density(temperature) - kg/m3 (K, Pa)

• Kerosene_viscosity(temperature): K

Usage

testdata_MB

Format

An object of class list of length 10.

Examples

testdata_MB$Kerosene_viscosity(283.15)     # Kerosene Viscosity at 10 degC

density_air <- function(temperature, pressure) {
  testdata_MB$ideal_gas_density(temperature, pressure, testdata_MB$Mair)
} 
density_air(293.15, 5*100000)  # Air density at 20 degC and 5 bar
