Why is the back-work ratio much higher in the brayton cycle than in the rankine cycle?
Ivanshal [37]

The back-work ratio much higher in the brayton cycle than in the rankine cycle because a gas cycle is the Brayton cycle, while a steam cycle is the Rankine cycle. Particularly, the creation of water droplets will be a constraint on the steam turbine's efficiency. Since gas has a bigger specific volume than steam, the compressor will have to work harder while using gas.

Recall the steady flow device's shaft work expression.

W =-∫ V dP +...

As it is in the pump (liquid) compared to turbine (superheated vapor) in the Rankine cycle, the specific volume in the compressor is not significantly less than the specific volume in the turbine in the Brayton cycle.

A thermodynamic cycle that transforms heat into mechanical energy is the Rankine cycle, often known as the Rankine vapor cycle.

The operation of various heat engines that use air or another gas as their working fluid is described by the Brayton cycle, a thermodynamic cycle.

Recombinant DNA uses what medium to produce new genes?
mestny [16]

The genetic characteristic of two different organisms are induced into a new host organism for the purpose of producing new genes.

<u>Explanation:</u>

In the field of bio technology, Recombinant DNA technology plays a very important role. This helps in the production of genes. The first thing insulin of human was produced with this technology. In this technology, the gene that is to be produced is cut and it is placed inside a host organism where it gets multiplied.

This technology uses five steps in gene production. Firstly, the DNA that is essential will be cut. this is done by restriction site. PCR is used secondly in order to amplify the copies of the genes. Then these are induced into Vectors after which they will again be introduced into a host organism. Then finally the results will be the genes of the desired characteristics.
