In a machining operation using a horizontal boring machine, assume that sensors have been installed to measure cutter vibration (v), product surface roughness (s), product dimensional accuracy (a), and cutter temperature (t), and assume that the sensors send the following digital signals:
v =1 for excessive vibration
t =1 for high temperature
s =1 for poor product surface
a =1 for poor quality
Otherwise these signals are ‘0’s. Design a logic circuit which has two outputs, codes yellow (Y) and red (R). Code yellow is a "1" if any one of the sensor signals is a 1. The code red is a "1" if more than one of the sensor signals is 1; otherwise both outputs are ‘0’s.
Conditions and outputs
i. Yellow when any of the signal is 1
ii. Red when more than one signal is 1
What will be an ideal response?
A) What is the efficiency of the compressor? B) If the refrigerator is required to produce 300 kJ/min of cooling, what is the required flow rate of refrigerant in mol/min? C) What is the coefficient of performance of the refrigeration cycle?
A refrigerator operates using the vapor-compression cycle. The steady-state refrigeration cycle and the physical properties of the refrigerant are summarized here: ? A boiler produces saturated vapor at P=0.03 MPa and T=5 °C, which has a specific enthalpy of 30 kJ/mol. ? The vapor is compressed to P=0.09 MPa. The ACTUAL temperature of the gas leaving the compressor is T=35 °C. ? The vapor is then condensed into saturated liquid at P=0.09 MPa, which has a specific enthalpy of 15 kJ/mol. ? The liquid enters a valve and experiences a pressure drop to P=0.03 MPa. ? The refrigerant then enters the boiler. The ideal gas heat capacity can be considered constant at CP*=15R.
