The thermal entrance length for a fluid with a Prandtl number greater than one will be longer than the hydrodynamic entrance length, and shorter if the Prandtl number is less than one. For example, molten sodium has a low Prandtl number of 0.004, [12] so the thermal entrance length will be significantly shorter than the hydraulic entrance length.

Developed and administered by the Educational Records Bureau (ERB), the ISEE has four levels: [1] the Primary level, for entrance to grades 2–4; Lower level, for entrance in grades 5–6; Middle level, for entrance in grades 7–8; Upper level, for ...
The f-number (also called the ' relative aperture '), N, is defined by N = f / E N, where f is the focal length and E N is the diameter of the entrance pupil. [2] Increasing the focal length of a lens (i.e., zooming in) will usually cause the f-number to increase, and the entrance pupil location to move further back along the optical axis.
At 11+, Common Entrance consists of two English examinations, as well as an examination each in Mathematics and Science. [3]At 13+, Common Entrance consists of examinations in Mathematics (three papers: a (listening) mental mathematics paper, plus written non-calculator and calculator); English (two papers); and one paper each in Latin, Classical Greek, Geography, History, Religious Studies ...
Fields in the Natural Science includes Biology, Chemistry, Mathematics, Physics, while Geography, Social Studies, history in the Social Science. The other general subjects are mandatory to both streams such as English, Physical Education and national and foreign language subjects. And it's scored out of 600 for both natural and social stream [5]
The latest structure includes two sections, i.e. A and B, in all four subjects, namely Physics, Chemistry, Botany, and Zoology. Section A comprises 35 mandatory questions, while Section B contains 15 questions, out of which 10 questions are to be answered, leading to a total of 200 questions, with 180 questions that can be answered.

A few British universities have lost confidence in the grades that are awarded by secondary schools, and require a few applicants to sit for a competitive entrance examination or other aptitude test. According to the Schools Minister, "strong evidence has been emerging of grade inflation across subjects" in recent years. [4]
