Tolits is working on a restaurant famous for its bulalo soup. His end of shift is 5:00 pm and needs to go home by that time to pick up his wife, Marites for their anniversary date. A customer made a reservation at 5:15 pm and wants his bulalo soup to be ready at that exact time. To ensure the quality of the soup, it should be served at a temperature which is exactly 88° C. Tolits needs to prepare the bulalo before the end of his shift. Initially, as Tolits is preparing the bulalo soup, its temperature is 23°C and placed on a pan heated at 154° C. After 5 minutes, its temperature is 33°C. The bulalo soup is done (cooked) once its temperature is 120° C. Tolits found out that cooling it in a sink full of cold water, while the faucet is running with the water resulting to roughly constant temperature of 25° C, could bring the temperature of the bulalo to 88°C to be ready at 5:15 pm. How many minutes before the end of the shift of Tolits should he start cooking bulalo so that he is done before 5:00 pm and his co-worker can serve it at 5:15pm?

bliuzodt to mopolb 9. If machine parts are degreased by means of kerosene as shown in the diagram, how much kerosene make-up is needed per day? How much kerosene has to enter the degreasing vat per day? There are about 3 lb of grease per 100 lb of machine parts, and 60 tons of machine parts are processed each day. Five thousand pounds of kerosene (the 10% solution) are carried away by the machine parts each day but drip off and are caught and put back in the degreasing vat. Two hundred pounds of the 10% solution are lost each day from the vat by evaporation, spillage, or by being carried away.
Alden and Arden are trying to figure out the boiling point of water for a science experiment. To do this, they have a glass of water, timer, stove and will change the temperature of the water until it boils. They initially set the stove at 113ºF and adds 410F for the 1st minute. They continuously added 410F every minute until it reaches the boiling point of water. They noticed that it takes 11 minutes after the initial first minute to reach the boiling point, which they found out to be at 212ºF. Is their experiment correct? Help them prove analytically.
Q3) On a hot summer day, a student turns his fan on when he leaves his room at 9.00 am. When he returns at 1.00 pm, will his room be warmer or cooler than the neighboring rooms? Why? Assume all the doors and windows are kept closed.
The brewing process involves 4 steps. Boiling, Fermenting, Filtering and Kegging. The batch size is 100 gallons for the boil and fermentation tanks. Process times for the different steps are Boiling: 8 hours/100 gal, Fermenting: 15 days/100 gal, Filtering: 10 gal/hour, Kegging 10 min/5 gal. In order to improve the productivity they decide to introduce a holding tank between the fermentation and filtration steps. They are able to drain the fermentation tank at a rate of 30 gal/hour. Ferment WIP Keg Boil Filter What is the minimum WIP tank size they need? (Round your answer to the nearest 10 gallons) Assume 24 hours/day

3. According to Newton's cooling law, the rate of cooling of a hot body is pro- portional to the difference between the temperatures of the hot body and the environment. If the room temperature is 35°C and the temperature of a hot body in the room cools down to 55°C from 105°C Celsius in just 6 minutes, then how many more minutes will it take to cool down to 45°C?
