Aflowrate measuring device is installed in a horizontal pipe through which water is flowing. a u-tube manometer is connected to the pipe through pressure taps located 3 in. on either side of the device. the gage fluid in the manometer has a specific weight of 112 lb/ft3. determine the differential reading of the manometer corresponding to a pressure drop between the taps of 0.5 lb/in2.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
