The fresh feed to an ammonia synthesis reactor contains nitrogen, hydrogen and 2.0 mole per cent inerts. The molar ratio of H2:N2 is 3:1. The product stream consists of pure ammonia. Since conversion in the reactor is only 15%, a recycle stream is used and in order to avoid build-up of inerts, a purge stream is withdrawn. The rate of purge stream is adjusted to keep inert concentration in the recycle stream at 8 mole per cent. For a fresh feed rate of 100 moles/hr. Note that recycle stream contains only nitrogen, hydrogen and inerts. The N2:H2 ratio of 1:3 is maintained in every process stream, and calculate the moles of nitrogen entering the reactor and in the recycle stream?

The following question, there are three statements I, II and III. Read the question carefully and mark your answer according to which statements(s) is/are sufficient to the answer the question. What is the Speed of the stream? Statement I: The distance between two points A and B is a km and the boat cover 90km along the stream in 5 hours. Statement II: The distance travelled along the stream is four times the total distance and that against the stream is three times the total distance Statement III: The total time taken against the stream is 10% more than that along the stream
In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: Superman and Batman in their boat are moving towards each other If Superman travel against the stream and Batman along the stream they are at a distance of 2300 km from each other. If the Speed of Stream is 20 km/h and Speed of Superman’s Boat is 100 km/h and Speed of Batman’s Boat is 130 km/h. Find the Time Taken to meet each other Quantity B: Tony Stark is flying in his suit 1 hour before Captain America with the speed of 200 km/h. If Captain America is chasing him in the boat which runs at a speed of 270 km/h against a stream which has speed of 20 km/h. Find the time in which he catches the Tony Stark.
Consider the following statements in connection with deflection-type and null-type instruments: 1. Null-type instruments are more accurate than the deflection-type ones. 2. Null-type of instrument can be highly sensitive compared to a deflection-type instrument. 3. Under dynamic conditions, null-type instruments are less preferred to deflection-type instruments. 4. Response is faster in null-type instruments as compared to deflection-type instruments. Which of the above statements are correct?
What is the distance covered by boat N upstream in 5 hours? Which of the following option is sufficient alone to find the answer? A) Boat M is travelling downstream with 20% more downstream speed of boat N. Speed of boat M in still water is 10% more than the speed of boat N in still water. B) Boat M and Boat N are travelling downstream with speed 33 km/hr and 40 km/hr respectively and speed of boat M is still water is 2 times the speed of stream. C) Speed of boat M in still water is 6 km/hr less then speed of boat N in still water and speed of stream is 10 km/hr. D) Speed of stream is ½ times the speed of boat N in still water and downstream speed of boat M is 44 km/hr. E) Speed of stream is 10 km/hr and ratio of upstream speed of boat M and boat N is 3 : 2 respectively.
Consider the following statements with reference to Jet stream. 1. The Jet Stream is a geostrophic wind. 2. There are two permanent jet streams – subtropical jets at mid-latitudes and polar front jets at lower latitudes. 3. Temperature also influences the velocity of the jet stream. The lower the difference in air temperature, the faster the jet stream. Which of the statements given above is/are NOT correct?
Consider the following grammar and the semantic actions to support the inherited type declaration attributes. Let X1, X2, X3, X4, X5 and X6 be the placeholders for the non-terminals D, T, L or L1 in the following table: Production rule Semantic action D → T L X1.type = X2.type T → int T.type = int T → float T.type = float L → L1, id X3.type = X4.type addType(id.entry, X5.type) L → id addType(id.entry, X6.type)   Which one of the following are the appropriate choices for X1, X2, X3 and X4?
Consider the following grammar (that admits a series of declarations, followed by expressions) and the associated syntax directed translation (SDT) actions, given as pseudo-code: P → D* E* D → int ID {record that ID.lexeme is of type int} D → bool ID { record that ID.lexeme is of type bool} E → E1 + E2 {check that E1.type = E2.type = int; set E.type := int} E → !E1 {check that E1.type = bool; set E.type := bool} E → ID {set E.type := int} With respect to the above grammar; which one of the following choices is correct?
