A robot arm is moving in a defined space. Using ultrasonic sensors calculate the coordinate of the robot end effector position. A transmitter T1 is attached at the end effector of the robot arm and two receivers R1 and R2 are placed 2m away from each other as shown in Figure. The speed of sound is 340m/s in the air. R1 detects signal from the transmitter T1 after 5ms and, R2 detects signal from the transmitter T1 after 3ms. Using a triangulation method calculate the end effector x and y coordinate of the robot arm.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
