Chapter 7, Problem 7.81P

Dry saturated steam at a pressure of 10 bar enters in a nozzle and is discharged at a pressure of 1.5 bar. Find the final velocity of steam when the initial velocity is negligible. If 10% of the heat is lost in friction in divergent part find the percentage reduction in the final velocity.

6.17 : A centrifugal compressor running at 2000 rpm receives air at 17°C and if the outer diameter of blade tip is 750 mm. Find temperature of air leaving the compressor. Take C, = 1kJ/kgK. %3D

Please help me answer this problem with complete solution and figure PROBLEM: A fireman reduces the exit area on a nozzle so that the velocity inside the hose is quite small relative to the existing velocity. What is the maximum exiting velocity and what is the maximum height that the water can reach if the pressure inside the hose is 700 Kpa?

1. define the cutfof ratio and the compression ratio     2. air is compressed at a constant temperature find the word done on the fluid under the: - initial pressure 200 kpa - final pressure 1500 kpa   - compression temperarture 600 k

A single-stage single acting air compressor takes air in at 1 bar & delivers at 6.5 bar. Work done by the compressor is 36 kJ and the compressor runs at 150 rpm. Calculate the power required in kW. the power required in kW. Answer

A multistage air compressor compresses air from 1 bar to 40 bar. The maximum temperature in Ony stage is not to exeed 400k. If the law. of compression for all the stages is putes, const and the initial temperature is 300k, find the i) Number of stages for minimum power Intermediate pressure for optimum compression as well as the power needed

3- Steam initially dry and saturated is expanded in a nozzle from 12 bar to 0.95 bar. If the frictional loss in the nozzle is 10% of the total heat drop, calculate the mass of steam discharged when exit diameter of the nozzle is 12 mm.

Fast.

Problem 2: A turbine accepts steam at 3000kPa and 800 °C and leaves at 100 kPa with a quality of 30%. If the Criss flow rate is 5 he's determine the power puput. (Neelect kinetic & potential energy changes. Neglect heat kg/s
