A thermocouple is submerged in water contained inside a beaker of 5.0 cm diameter and a height of 7.0 cm. An immersion heater with a maximum power of 300 W is used to heat the water to the set temperature of 80°C. Calculate the steady-state temperature error for values of DT of 3, 5, and 10. Assume that the convective heat transfer coefficient between the beaker and environment is h = 45 W/m2K and the environment temperature is 25°C.

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
