lab week 4 AP IV

In measuring the surface tension of a liquid (drop weight method), 20 drops of the liquid (r = 0.2cm) falling apart from the tip whose diameter is 0.4 cm were found to weight 0.95 gram. What is the surface tension of the liquid?

Can anyone help me with these questions please

Need help filling out the table with the data I have (1st row is fine but show work please)

(b) A special sprinkler system is comprised of three identical humidity sensors, a digital controller, and a pump, of which the reliability is 0.916, 0.965, and 0.983 respectively. The system configuration is shown in the figure below. Sensor Controller Pump Reliability block diagram of a sprinkler system. (b) Calculate the reliability of the sprinkler system. (c) Discuss the importance of safety in an engineering maintenance.

Can anyone help me with this question

I received an answer for my last question and I am still a bit confused. In the solution you said that F only has a horizontal component, how did you arrive at that? The question says that F is down and to the left.

The tank is connected to a large steam line carrying steam at 200 Ibf/in?, 450°F. Steam flows into the tank through a valve until the tank pressure reaches p2 = 120 lbf/in? and the temperature is 400°F, at which time the valve is closed. Steam at 200 lbf/in.². 450°F Tank Valve (1) Initially: 30 lbfin.?, mı = 25 lb |(2) Finally: Ibfin.?, 400°F.
