Affinity laws describe the relationship between pump performance and speed, flow rate, and head.
Affinity laws state that if the speed of a pump is changed, the flow rate and head will also change proportionally.
The laws can be used to predict the performance of a pump at different speeds without having to conduct actual tests.
The three affinity laws are: 1) Flow rate is proportional to speed, 2) Head is proportional to...
NPSH is calculated by subtracting the vapor pressure of the fluid from the absolute pressure at the pump suction.
NPSH stands for Net Positive Suction Head.
It is a measure of the pressure required at the suction of a pump to avoid cavitation.

The recommended pipe material for 48% NaOH is high-density polyethylene (HDPE) or polyvinyl chloride (PVC).
48% NaOH is a highly corrosive substance that can cause damage to certain pipe materials.
HDPE and PVC are resistant to the corrosive effects of NaOH and are commonly used for transporting this chemical.
Other materials such as steel or copper should be avoided due to their susceptibility to corrosion.
The temperatur...

Expansion joints to compensate for thermal expansion
Flow meters to measure the flow rate
Duplex stainless steel is good for NaCl 2500 ppm fluid due to its high corrosion resistance and strength.
Duplex stainless steel has a high resistance to corrosion and pitting
It has a high strength and toughness
Other materials like carbon steel and copper alloys may corrode in NaCl solutions
The gradient required for free flow in a sewage pipe depends on the pipe diameter, flow rate, and type of material used.
The gradient should be steep enough to ensure that the sewage flows freely without any blockages or backups.
The gradient is typically expressed as a percentage or ratio of the vertical drop to the horizontal distance.
For example, a gradient of 1:100 means that for every 100 meters of horizontal distan...

Deflection diagram for frames shows the displacement of each point along the frame under load.
Deflection diagrams are used to visualize how a frame deforms under load.
They show the displacement of each point along the frame in response to applied loads.
The shape of the deflection diagram can help engineers analyze the structural integrity of the frame.
Common types of deflection diagrams include bending moment diagrams
Bending moment diagram shows variation of bending moment along the length of a frame.
Bending moment diagram helps in analyzing the internal forces in a frame.
It is plotted with distance along the frame on x-axis and bending moment on y-axis.
Points of zero bending moment indicate locations of maximum bending moment.
The diagram can be used to determine the critical sections of a frame.
Example: A simply supported beam wil...
Bearing articulation for curved spans involves designing bearings that can accommodate the movement and rotation of curved structures.

Rigid pile caps are designed to transfer the load from the superstructure to the piles. The design should consider the pile arrangement, load distribution, and soil properties.
The pile cap should be designed to distribute the load evenly to the piles.
The pile arrangement should be considered to ensure that the pile cap is not overloaded.
The soil properties should be analyzed to determine the bearing capacity of the pil...
Prestressing losses occur during the transfer of prestress from the jacks to the concrete. These losses can be divided into two stages.
The first stage is immediate losses, which occur due to friction between the strands and the ducts, anchorage slip, and elastic shortening of the concrete.
The second stage is time-dependent losses, which occur due to creep and shrinkage of the concrete, relaxation of the steel, and temp...

Post-tension involves inserting steel cables or bars into hardened concrete and then tensioning them to create compression in the concrete.
Pre-tension is typically used in precast concrete ele...
Analysis and design of piles involves determining the load capacity and selecting the appropriate type of pile for a given soil condition.
Pile load capacity is determined through various methods such as static load tests, dynamic load tests, and pile integrity tests.
