Objectives. The Loeb minimum criteria (LMC), developed by a 2001 consensus conference, are minimum standards for initiation of antibiotics in long term care settings, intended to reduce inappropriate prescribing.
NTP-Normal Temperature and Pressure. NTP is commonly used as a standard condition for testing and documentation of fan capacities: 1  NTP-Normal Temperature and Pressure-is defined as air at 20oC (293.15 K, 68oF) and 1 atm (101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 29.92 in Hg, 407 in H2O, 760 torr).ote that the earlier IUAPC definition of STP to 273.15 K and 1 atm (1.01325 105 Pa) is discontinued. 1 Pa = 10-6 N/mm2 = 10-5 bar = 0.1020 kp/m2 = 1.02x10-4 m H2O = 9.869x10-6 atm = 1.45x10-4 psi (lbf/in2). Standard volume of 1 mole of an ideal gas at STP is 22.4 liters.
Water content is defined as the absolute humidity of the gas if it is brought to a standard pressure and temperature state. For metric units this state is normal ambient pressure (101325 Pa) and 0 Â°C. For nonmetric units (lb/MMscf) the standard temperature is 60 Â°F.t is a function only of temperature, and it indicates the maximum amount of water that can exist in the vapor state. This amount increases with increasing temperature. Vaisala Humidity Calculator uses the Wagner, Pruss pruÃ formula to calculate the water vapor saturation. pressure
