This set of MCQs helps students to learn about pump which is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy and pumps further can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps and pumping
Which of the following is the correct classification of pumps?
Which of the following pump is classified based on the type of service?
Which of the following pump is based on the type of power?
Consider the following statements. i. Capacity of the pump ii. Number of pump units iii. Discharge condition The selection of a particular type of pump depends on which of the following?
The centrifugal pump has a ______ flow.
Based on the type of casing, the centrifugal pump is divided into _____ types.
Which of the following type of pump is based on the number of entrances to the impeller?
Depending on the number of impellers, the centrifugal pump is divided into ______________ types.
Consider the following statements regarding vortex chamber. i. Reduce the velocity of the pump ii. Convert pressure energy into kinetic energy iii. Decrease the efficiency of the pump Which of the above statement is correct?
