How tight should valve stem seals fit? The proper umbrella seals should fit suggly on the head and firm enough on the stem to hold onto the valve and prevent any seepage down the stem. You will always hear a little air leaking. What is a positive valve stem seal? Positive seals attach to the […]
Why is it important to study the characteristics of fault system?
Why is it important to study the characteristics of fault system? To understand the risk that different areas of the U.S. face for earthquake hazards, we need to know where faults are and how they behave. We know a fault exists only if it has produced an earthquake or it has left a recognizable mark […]
What are double pipe heat exchangers used for?
What are double pipe heat exchangers used for? Double-pipe heat exchangers are used in many industries because of their low design and maintenance costs, flexibility, and low installation costs [25]. They are mainly used for sensible heating or cooling of process fluids in applications of small heat transfer areas of up to 50 m2 [38]. […]
What is an advantage of a closed loop system over an open loop system?
What is an advantage of a closed loop system over an open loop system? Closed-loop control systems have many advantages over open-loop systems. One advantage is the fact that the use of feedback makes the system response relatively insensitive to external disturbances and internal variations in system parameters such as temperature. What are the advantages […]
How close can you work to overhead power lines?
How close can you work to overhead power lines? You should manage the risks if you intend to work within a distance of 10 m, measured at ground level horizontally from below the nearest wire. 12 The most effective way to prevent contact with overhead lines is by not carrying out work where there is […]

How do I create a location plan?
How do I create a location plan? The following steps will help you on how to draw your site plan: Step 1: Determine property boundaries and lot dimensions before drawing a site plan. Step 2: Determine the location of structures and other site features in relation to the property boundaries before you draw a site […]
What are some ways that the strength of an electric field between two parallel plates can be increased?
What are some ways that the strength of an electric field between two parallel plates can be increased? Increasing the charges of the plates, by increasing the battery strength it will increase the plate charges. In addition, decreasing the distance between two plates, increases the strength of an electric field between two plates. Where is […]
What is the isentropic efficiency of a turbine?
What is the isentropic efficiency of a turbine? Hence, the definition of isentropic efficiency of turbine is the ratio of the actual work output of the turbine to the work output of the turbine if the turbine undergoes an isentropic process between the same inlet and exit pressures. Compressors and pumps, when undergo a steady-flow […]
