WebApr 30, 2024 · What is Qmax? While we measure the total volume of the urination is in mL (milliliter), the flow rate is measured in mL/second, and the Qmax is the value of the highest flow rate measured during the test. In other words, Qmax is the fastest stream measured in mL/s. Weak flow = Low Qmax Slow urination speed = Low Qmax Flat urination chart = … WebQ max – maximal Cooling Capacity corresponding to ∆Tmax=0. I max – the device Current at ∆Tmax. U max – the terminal Voltage for Imax with no heat load. Usually manufacturers specify TE cooler performance parameters at 300K (27ºC) ambient temperature in vacuum or/and at 323K (50ºC) in dry Nitrogen (N2) conditions.
