Draw a diagram of a typical BDP flame above an AP/HTPB composite propellant. Label each flame, and include the position of the AP and HTPB in the condensed phase.

For the given set of strand burner data (given also as a .txt for easy excel import):

Calculate the parameters, a and n, of St. Robert’s Law for each T0. Plot the results in log-log space.

Calculate the temperature sensitivity of the propellant, σ_p at P=0.5 MPa, P=5 MPa, and P=10 MPa.

A 35-kg box of beef at 6 C having a water content of 60% is to be frozen to a temperature of -20 C in 3 h. Determine:

a) the total amount of heat that must be removed from the beef

b) the average rate of heat removal from the beef

When a fuze ( note this spelling) of some sort is ignited it will burn or deflegrate ( be sure you know the difference) In some cases when then the chemical composition of the fuze material is a propellant or even an explosive of some type the fuze will transition to a detonation within that material. The question is what attributes of the the material - Chemical and Geometric - will govern if or how or how quickly the material detonate?

An Internet service provider has three different subscription packages for its customers:

Package A: $9.95 per month 10 hours of access are provided.   Additional hours are $2.00 per hour.

Package B: $14.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour.

Package C: $19.95 per month unlimited access is provided.

Write a MATLAB script to calculates a customer’s monthly bill. It should ask which package the customer has purchased and how many hours were used. It should then display a message with the hours and the total amount due, correct to two decimal places.

Also displays how much money Package A customers would save if they purchased packages B or C, and how much money Package B customers would save if they purchased Package C. If there would be no savings, no message should be printed.

Input Validation: Be sure the user only selects package A, B, or C. Also, the number of hours used in a month cannot exceed 744. Display an error message and exit the program if user enters incorrect information.

Find the design cooling and heating loads of UC 1017. Consider UC 1017 is a detached room. You are free to assume any values reasonably for the calculation. Consult different charts, tables and climate data as necessary. Assuming 50% fresh air and 50% of recirculated air passing through the evaporator coil and the by-pass factor of 0.2, find the dew point temperature of the coil and the capacity of the coil.

I need you to provide the Table and the calculation for everything.

the room size = Hight 6.6 m , width 18m, length 14.5m

I'll attach an example for a student work from last year that I'd like you to follow.

Address the following questions related to heat exchanger effectiveness. Recall that the maximum heat transfer possible is the product of the minimum heat capacity (mass flow rate times specific heat) times the difference between the hot and cold side inlet temperatures. a. sketch the temperature profiles for a 50% and 80% effectiveness heat exchanger. make sure you have the correct shape which includes the degree of steepness at each end. b. What is the effectiveness for a heat exchanger with the following characteristics: the hot side is water entering at 160F and 21Ib/s, and the cold side is air entering at 20F and 4Ib/s. the heat exchanger has been designed to achieve an air outlet of 110F.

1. An aluminum air-cooled engine cylinder head for a single cylinder, 2-stroke engine is to

be die-cast. The overall diameter of the cylinder head is 101.6 mm. If the projected

plan area of the runners and gating system is 100 mm2 and the casting pressure is 10

MPa (1500 psi), what minimum locking force is required for the die-casting machine in kN.

A high-school classroom is occupied by 20 students who each produce 180 Btu/h (53 W) of sensible heat and 0.20 lb/h (0.09 kg/h) of moisture. The class is to be maintained at 68°F (20°C) and 55% relative humidity. Conditioned air is supplied at 60°F (15°C) to meet the sensible and latent loads. What is the SHR? To meet the loads, what must the humidity ratio and mass flow rate of the supply air be? The office is located at 5000 ft (1500 m) altitude.

A pot with boiling water at 100 C, if the handle is 3 mm thick, 22 mm wide, 300 mm long and exposed tp 19 C temp, h= 5 w/m2 c.

What is the temp at the end of the handle if it is k= 13, and then if it was k = 180 W/m.k

What kind of assumptions

Does insulation need to be on the intire handle from being burned why?
