The influence of width-to-pitch ratio (t/p) and width-to-height ratio (t/e) of ribs upon heat transfer and total pressure loss of rectangular grid-ribbed channel was studied experimentally.

The study involves the distribution of total pressure loss factor, outlet gas flow static pressure and Mach number along the blade height.

An experimental investigation has been carried out to reveal the variations of total pressure loss and static pressure recovery with the inner and outer dump angles and the distance between prediffuser exit and the head of the flame tube (i.

Taking the object of transporting carbon black,analyzed the transportation pressure losing of level pipe、vertical pipe and bend pipe of the pneumatic transportation pipe line,gained the pres-sure losing formula of the three sorts of pipe line.

The result showed the pressure losing with two times draught was slightly lower than that with no two times draught's while empty running.

According to pressure losing coefficient of hydraulic system parts tested by experiment, the advancing velocity of powered support was calculated under a certain condition.
