Also, viscous media can not be applied, and that specific product for the medium viscosity range is relatively narrow.
另外，粘稠状介质不能适用，而且，特定的产品适用的介质粘度范围相对较窄。
So choose stainless steel high viscosity pump is must indicate the specific temperature, and medium lubricity.
所以选择不锈钢材质的高粘度泵是一定要注明具体的使用温度，及介质的润滑性。
Under the same wall heat condition, with the increase of momentum correction coefficient, viscosity loss of the nozzle increases, but thrust and specific impulse decrease.
在同等壁面热条件下，随着动量调节系数的增加，喷管粘性损失增大，喷管的推力和比冲都将下降；
