i. Pycnometer is a device used to determine the of a liquid. ii. Losses in Globe valves are than losses in gate valves for the same flow rate. iii. Losses in sudden contractions are than losses in sudden expansions for the same ratio of areas. iv. Barometer is a device used to measure v. The efflux time for a liquid in tank is proportional with the length of the exit pipe. vi. By increasing flow rate, the volumetric efficiency of a piston pump vii. A manometer is a device for measuring viii. The dependence of pressure drop in a pipe on the length of the pipe is than on the diameter of the pipe. ix. In digital joule meter experiment, at constant voltage, as the mass lifted by the motor increases, the efficiency of the motor x. In fan experiment the suction pressure is then the
