Astudent makes two measurements with the manometer. the first measurement is with 100 mm of water in the tube and the plc displays the digital value in n7: 0 = 978. the second measurement is with 800 mm of water in the tube and the digital value in n7: 0 = 7750. write a one run plc program using the scp command to scale the value in n7: 0 back into mm units and store the answer in n7: 4.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
