Practical Process Control for Engineers and Technicians ... The resistance constant R will be H/Q2 = 2 m/5 m 3 /hr = 0.4 hr/m2 and the time constant will be AR = 0.8 hrs. The gain for a change in Q1 will also be R. Hence if we make a small corrective change at Q1 of say 0.1 m 3 /hr the resulting change in level will be: R.Q1 = 1 x 0.4 = 0.4 m and the time to reach 98% of that change will be 3.2 hours.

RR Lyrae variable - Wikipedia RR Lyrae variables are periodic variable stars, commonly found in globular clusters.They are used as standard candles to measure (extra) galactic distances, assisting with the cosmic distance ladder.This class is named after the prototype and brightest example, RR Lyrae. They are pulsating horizontal branch stars of spectral class A or F, with a mass of around half the Sun's.

Hypergiant - Wikipedia A hypergiant (luminosity class 0 or Ia +) is a very rare type of star that has an extremely high luminosity, mass, size and mass loss because of its extreme stellar winds.The term hypergiant is defined as luminosity class 0 (zero) in the MKK system.However, this is rarely seen in the literature or in published spectral classifications, except for specific well-defined groups such as …
