What is nominal torque gearbox?
What is nominal torque gearbox? The most common torque and often the most important is the nominal torque. This is the torque that can transmit a gearbox for a long time without any interruption. This torque is also called RMS torque (Root Mean Square) and can be calculated using the formula listed in our catalogues. […]

What is lumped system analysis when is it applicable?
What is lumped system analysis when is it applicable? The temperature in this process is considered to be uniform at a given time. Such an analysis is called Lumped parameter analysis because the whole solid, whose energy at any time is a function of its temperature and total heat capacity is treated as one lump. […]
What does it mean when you calculate a 95% confidence interval?
What does it mean when you calculate a 95% confidence interval? Strictly speaking a 95% confidence interval means that if we were to take 100 different samples and compute a 95% confidence interval for each sample, then approximately 95 of the 100 confidence intervals will contain the true mean value (μ). Consequently, the 95% CI […]
How do you find the coordination number of cation and anion?
How do you find the coordination number of cation and anion? Unequal Coordination Number Example Titanium oxide (TiO2) is an example of a crystal structure containing anions and cations in a 2:1 ratio. So, the fundamental unit of the lattice is tetrahedral: Each Ti4+ cation is amid six O2-ions, while every O2-ion has three immediate […]
Which flow type is the most efficient flow type?
Which flow type is the most efficient flow type? Counter flow heat exchangers are the most efficient of the three types. In contrast to the parallel flow heat exchanger, the counter flow heat exchanger can have the hottest cold- fluid temperature greater than the coldest hot-fluid temperatue. Can log mean temperature difference be negative? According […]
