Igarashi Motors Interview Questions and Answers

Use a positive displacement pump to transfer the liquid slowly and avoid agitation.

• Select a positive displacement pump that can handle highly viscous liquids.

• Transfer the liquid slowly to avoid agitation and bubble formation.

• Use a pump with a low shear rate to prevent damage to the liquid.

• Consider using a pump with a pulsation dampener to further reduce agitation.

• Ensure that the vessels are properly connected and sealed to prevent leaks.

The Navier-Stokes equation describes the motion of fluid substances.

• The Navier-Stokes equation is a set of partial differential equations that describe the motion of fluid substances.

• It takes into account the conservation of mass, momentum, and energy.

• The equation includes terms for pressure, viscosity, and acceleration.

• It is used in many fields, including engineering, physics, and meteorology.

• The equation is named after Claude-Louis Navier and George Gabriel Stokes, who inde...read more

Deriving the continuity equation

• Continuity equation states that mass cannot be created or destroyed, only conserved

• It relates the mass flow rate, density, and velocity of a fluid

• The equation is derived from the principle of conservation of mass

• The equation can be applied to both steady and unsteady flow

• The continuity equation is important in fluid dynamics and engineering

Continuity equation for compressible flow

• The continuity equation states that mass cannot be created or destroyed in a flow system

• For compressible flow, the equation takes into account changes in density due to changes in pressure and temperature

• The equation is expressed as: ∂(ρ)/∂t + ∇(ρv) = 0

• ρ is the density, t is time, v is velocity, and ∇ is the divergence operator

• The equation can be used to analyze fluid flow in a variety of applications, such as aerodynamics and gas dyna...read more

Air compressor and refrigeration cycle are two different systems used for different purposes.

• Air compressor is used to compress air and increase its pressure for various applications such as pneumatic tools, HVAC systems, etc.

• Refrigeration cycle is used to remove heat from a space or substance and maintain a lower temperature.

• Both systems use similar components such as compressors, condensers, evaporators, and expansion valves.

• In an air compressor, the compressed air is store...read more

Swinging of the cricket ball is the movement of the ball in the air due to the aerodynamic properties of the ball.

• Swinging occurs due to the difference in air pressure on either side of the ball.

• The side of the ball that is rougher creates turbulence in the air, causing the ball to swing towards that side.

• Bowlers use various techniques such as shining one side of the ball or applying saliva to create differential roughness.

• Swinging can be both inwards (towards the batsman) or...read more

A PID controller is a feedback control loop that calculates an error value as the difference between a desired setpoint and a measured process variable.

• PID stands for Proportional-Integral-Derivative

• It is commonly used in industrial control systems to regulate temperature, pressure, flow, and other process variables

• The proportional term responds to the current error value, the integral term responds to the accumulated error over time, and the derivative term responds to the r...read more

It depends on personal preferences and career goals.

• Consider the company culture and values

• Evaluate the job responsibilities and growth opportunities

• Research the industry and market trends

• Assess the compensation and benefits package

• Seek advice from current or former employees

• Example: If you value work-life balance, ITC may be a better fit as they offer flexible work arrangements. However, if you prioritize prestige and challenging projects, BCG may be more suitable.

• Example: I...read more
