Which of the following statements is correct concerning the viscosity of lubricating oil?()
A. Viscosity will increase as temperature increases
B. Viscosity is a measure of a fluid s internal resistance to flow
C. Viscosity will decrease as temperature decreases
D. Viscosity is not dependent on temperature
题目解答
答案
B. Viscosity is a measure of a fluid s internal resistance to flow
解析
粘度是流体内部阻力的度量,它描述了流体在流动时的阻力大小。对于润滑油而言,粘度是其关键特性之一。温度对粘度有显著影响,通常情况下,温度升高会导致粘度降低,而温度降低则会导致粘度增加。
