Answer:
A turbo blade has the best features from both other types of blade. The continuous, serrated edge makes for fast cutting while remaining smooth and clean. They are mostly used to cut a variety of materials, such as tile, stone, marble, granite, masonry, and many other building materials.
Explanation:
Answer:
avoid them by choosing not to drive if you expect severe weather.
The answer is 2,080 hours.
8x5=40
40x52= 2,080.
Answer:
the isentropic efficiency of turbine is 99.65%
Explanation:
Given that:
Mass flow rate of LNG m = 20 kg/s
The pressure at the inlet = 3000 kPa
turbine temperature at the inlet = ( -160+273)K = 113K
The pressure at the turbine exit = 300 kPa
Power produced by the turbine W = 120 kW
Density of LNG
The formula for the workdone by an ideal turbine can be expressed by:
We all know that density = mass * volume i.e
Then ;
replacing it into the above previous derived formula; we have:
However ; the isentropic efficiency of turbine is given by the relation:
99.65%
Therefore, the isentropic efficiency of turbine is 99.65%
