An orifice meter was calibrated for dry air at T=90 F and P=1.3 atm. The calibration data are as follow:
A piston cylinder contains 0.8kg of steam (water vapor) at 300 deg C and 1MPa absolute. The steam is cooled at constant pressure until half of the mass condenses.
A gate (shaped like .25 of a cylinder with radius R=3m) is used to control the flow of water through a canal.The height of the water in the tank is 30m. How much force must be applied to keep the gate from opening? The gate is 30m wide.
A 8 inch polyethylene pipe has a flow rate of 1000 gallons/minute with a linear length of 10000ft. Starting at elevation 200ft then ends at 600ft elevation. Initial pressure is 40 psi. find the friction and the head loss.
