CONTOH KASUS : Your boss claims that the scale will read the weight of the volume of water in the tank plus the tank weight, i.e., that we can treat this as a simple statics problem. You disagree, claiming that a fluid flow analysis is required. Who is right, and what does the scale indicate?

A jet of water issuing from stationary nozzle at 15 m/s (Aj = 0
A jet of water issuing from stationary nozzle at 15 m/s (Aj = 0.05 m2) strikes a turning vane mounted on a cart as shown. The Vane turns the jet through angle q = 500. Determine the value of M required to hold the cart stationary

Example 4.16 COMPRESSOR: FIRST LAW ANALYSIS
Air at 14.7 psia, 70F, enters a compressor with negligible velocity and is discharged at 50 psia, 100F through a pipe with 1 ft2 area. The flow rate is 20 lbm/s. The power input to the compressor is 600 hp. Determine the rate of heat transfer.
