a contracted horizontal weir placed within a concrete lined rectangular channel. A diversion channel branches off of the given rectangular channel 1,000 ft upstream of the weir. In order to provide the necessary discharge to the diversion channel, the flow depth at 1,000 ft upstream of the weir needs to be 3' when the discharge (Q) is 500 cfs. Determine the height that the adjustable head gate should be raised above the bottom of the weir (z

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
