A steam power plant operates on an ideal Rankine cycle with two stages of reheat and has a net power output of 60 MW. Steam enters all three stages of the turbine at 550°C. The maximum pressure in the cycle is 10 MPa, and the mini­mum pressure is 30 kPa. Steam is reheated at 4 MPa the first time and at 2 MPa the second time.

Determine

(a) the thermal efficiency of the cycle,
(b) the mass flow rate of the steam.

One of the benefits of working with chlorinated polyvinyl chloride (CPVC) pipe is that it can be cut with a variety of different tools that don’t require any electricity or heat. However, different cutting methods are preferred over others, depending on the application.

When cutting CPVC pipe, it is important to make a square, flat cut. An uneven cut limits the bonding area and weakens the fitting.

To help you make the best possible cut, we’ve put together the following dos and don’ts when cutting CPVC pipe in different situations.
