Vishwa Samudra Engineering Senior Engineer Mechanical Interview Questions and Answers

Gpm for water supply pump can be calculated by dividing the flow rate in gallons by the time in minutes.

• Calculate the flow rate in gallons per minute (GPM)

• Determine the time in minutes over which the flow rate is measured

• Divide the flow rate by the time to get the GPM value

Heat exchangers are devices used to transfer heat between two or more fluids, ensuring efficient heat transfer and temperature control.

• Transfer heat between fluids

• Maintain temperature control

• Increase energy efficiency

• Commonly used in HVAC systems, refrigeration units, and chemical processing plants

Alignment methods are techniques used to ensure proper positioning and orientation of mechanical components.

• Common alignment methods include laser alignment, dial indicator alignment, and straight edge alignment.

• Laser alignment uses a laser beam to measure and adjust the alignment of components.

• Dial indicator alignment uses a dial gauge to measure the alignment of components.

• Straight edge alignment involves using a str...read more

The questions cover various topics related to mechanical engineering, including transmission of a wheel loader, SAP PM working system, hydraulic diagram of an excavator, suspension system of a dumper, working of a Cummins engine, and common problems in truck gearboxes and differentials.

• Transmission of a wheel loader involves the transfer of power from the engine to the wheels through a series of gears and shafts.

The formula to calculate module in gears is the ratio of pitch diameter to the number of teeth.

• Module = Pitch Diameter / Number of Teeth

• Module is a measure of the size of the teeth on a gear.

• It is commonly used in gear design and manufacturing to ensure proper meshing of gears.

• For example, if a gear has a pitch diameter of 40 mm and 20 teeth, the module would be 40 mm / 20 = 2 mm.

Module is the ratio of pitch circle diameter to the number of teeth in a gear.

• Module is a gear parameter that defines the size of the gear teeth.

• Pitch circle diameter is the diameter of the imaginary circle on which the gear teeth are located.

• The formula M=D/T calculates the module where D is the pitch circle diameter and T is the number of teeth.

• For example, if the pitch circle diameter is 100 mm and the number of tee

Module in gears refers to the size of the gear teeth and is used to determine the gear ratio and dimensions of the gear.

• Module is the ratio of the pitch diameter to the number of teeth in the gear.

• It is used to calculate the dimensions of the gear teeth, such as tooth thickness and depth.

• Different gear modules are used for different applications, with larger modules for heavier loads and smaller modules for higher spee...read more

The pitch circle in gears is an imaginary circle that passes through the point where the teeth of two gears mesh together.

• The pitch circle is used to determine the gear ratio between two gears.

• It is the circle on which the pitch diameter of the gear is measured.

• The pitch circle diameter is used in calculations for gear design and analysis.

• The pitch circle is important for ensuring proper meshing of gears and smooth ope...read more
