The air velocity in the duct of a heating system is to be measured by a pitot-static probe inserted into the duct par- allel to the flow. if the differential height between the water columns connected to the two outlets of the probe is 2.4 cm determine (a) the flow velocity and (b) the pressure rise at the tip of the probe. the air temperature and pressure in the duct are 45°c and 98 kpa, respectively

On a average work day more than work place firs are reorted

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
