a solar dryer has been used to dry keropok lekor delicacy. the solar dryer with width of 1m withdraws a volume flow rate of 0.15 m/s under an ambient temperature of 37 °c. there is a solar collector attached to the solar dryer exposing to the heat from the sun. the solar collector has 3 m long, 1 m wide and 3 cm gap between the glass and base. the solar collector collects the heat from radiation for 365 w. calculate the temperature of the sensor t1 and t2. evaluate the system if keropok lekor required to dry at constant of 60 °c for 5 hours. ​
