Saturated steam at 100 °C condenses in a shell-and-tube heat exchanger (one shell pass, two tube passes) with a surface area of 0.5 m2 and an overall heat transfer coefficient of 2000 W/m2·K. Water enters at 0.5 kg/sec and 15 °C. Determine: a. the outlet temperature of the water (in °C) b. the rate of steam condensation (in kg/sec).

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

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
