Public health drawings are technical diagrams and plans that provide information about the plumbing and sanitary systems within a building or public facility. These drawings are crucial for ensuring proper sanitation, water supply, and waste management. Here's an explanation of the different types of public health drawings listed:

When the concrete is first mixed it is like 'bread dough'. It is soft and can be worked or moulded into different shapes. In this state concrete is called PLASTIC. Concrete is plastic during placing and compaction. The most important properties of plastic concrete are workability and cohesiveness. A worker will sink into plastic concrete. Concrete then begins to stiffen. The

Units are the vessels or basin that holds wastewater for the treatment by chemical or biological processes. They can be of any shape. Depending upon the flow and operating conditions and the methods of mixing of the wastewater therein, the reactors have the following main types; Continuous-Flow Stirred Tank Reactor (CFSTR) or Completely-Mix Reactor:

PDT is a substructure technique which includes applying slowly varying forces to a structural model. The motions and deformations observed in the test specimens are used to infer the inertial forces that the model would have been exposed to

In coning of wheel the tread or rim of wheels of railway vehicles is made in the shape of a cone with the slope of about 1 in 20. It maintains vehicle in the central position w.r.t. the track. On straight track, portions of wheels running on track have same diameter. While on curved path, the outer wheel has to cover larger distance than the inner wheel. Thus, the
